CARBON STEEL DIES Hex... Die Stock Tapping Geometry Straight Flute Taps contain most of the chip in the flutes, and can be used for through or blind holes. Spiral Point Taps push the chips forward, and are recommended for through holes. Taper Taps are used for starting threads in tougher materials. Bottoming Taps are used for blind holes to obtain the maximum length of thread. Plug Taps are suitable for either through or blind holes, where ample clearance remains between the thread the the bottom of the hole. How to Tap Effectively Successful tapping includes selecting the proper tap for the application. Consideration must be given to: The material to be tapped The material hardness Whether the hole is a through hole or a blind hole The depth or length of thread The percentage of thread Tap Set Section starting on page 50 38

52 Cutting Tool Information DRILLING Common Drilling Terms... Drill Reconditioning... Point Characteristics... Drilling - Cutting Speeds Table... Decimal Equivalent Charts TAPPING Common Tapping Terms... How to Tap Effectively... Tap/Drill Selector... Tap Speeds Selector Deep Hole Drilling When the hole depth is greater than three times the diameter, consider it a deep hole Step drilling, also called peck drilling, is the practice of drilling a short distance, then withdrawing the drill. This is often required to remove chips when drilling deep holes Peck drill just enough to prevent packing chips in the fl utes Chip congestion (eg: chips clogging the fl utes) is a major cause of drill failure General Drilling Considerations Stability is important. Instability can cause drill breakage of poor hole quality, including irregular or oversized holes To prevent work hardening, pay attention to speeds and feeds. Feed pressure should be constant. Do not peck until half-way through a deep hole. Use moderate speeds and a variable drill motor if possible. To prevent lock-up (grabbing of drill by material or workpiece at breakthrough), ease through the material by reducing speed and feed. See page 6 for Drill Troubleshooting Guide See page 36 for Tap Troubleshooting Guide Drill Point Characteristics Type Performance Benefits* Comments Conventional Point (118 ) General purpose Widely available Acceptable drill life Best suited in mild steel and aluminum Not self-centering; walking can occur on hard surfaces May produce burs on breakhrough GENERAL TOOL INFORMATION 52 Split Point (118 and 135 ) *Depends on application Self centering Excellent for portable drilling Longer drill life Good for drilling on curved surfaces Improved penetration rates Requires less effort Breaks up chips Best suited in alloy steels Difficult to regrind

53 Common Drilling Terms Axis The imaginary straight line which forms the lengthwise center of a drill Body The section of a drill from the shank to the outer edges of the cutting lips Body Clearance Diameter The portion of the land that has been cut away so it will not bind against the walls of the hole Chip Removal The ability of a drill to pull material that has been cut away from the point, up the flutes and out of the hole Chisel Edge The edge at the end of the web that connects the cutting lips Chisel Edge Angle The angle between the chisel edge and cutting lip, as viewed from the end of a drill Cobalt Steel A heat-resistant steel that produces increased drill life Drill Diameter The diameter over the margins of a drill, measured at the point (Dia.) Feeds Feed rates for drilling are determined by the drill diameter, machinability of materials and depth of the desired hole. Small drills, harder materials and deeper holes require additional considerations in selecting proper feed rates Flute Groove cut in the body of drills to provide cutting surfaces, permit removal of chips and allow cutting fl uid to reach cutting surfaces Flute Length The distance from the outer edges of the cutting lips to the extreme back of the fl utes Helix Angle The angle formed between the leading edge of the land and the axis of a drill High Speed Steel The high quality steel used in drills for most maintenance and industrial applications IPM Feed rate in Inches Per Minute = IPR X RPM IPR Inches Per Revolution (Feed) Land The outer portion of the body between two adjacent fl utes Land Width The distance between the leading edge and heel of the land, measured at a right angle to the leading edge Lip Relief Angle The relief angle at the outer corner of the lip Lip The cutting edge of a two-fl ute drill which extends from the chisel edge to the outer edge Margin The narrow raised surface on a drill body along the fl ute that stabilizes the drill in the hole Neck The section of reduced diameter between the body and the shank of a drill Overall Length The length from the end of the shank to the outer corners of the cutting lip Point The cone-shaped cutting end of a drill, made from the ends of the lands and the web Point Angle The angle of the cutting surfaces on a drill point, commonly 118 or 135 RPM Revolutions Per Minute = SFM SFM Dia. X 3.82 Surface Feet Per Minute = RPM X Dia. X.26 Shank The part of a drill by which it is held and driven Size Measurement reference for diameter size of a drill, expressed as either fractional, wire, letter or metric Speed The speed of a drill is determined by the rate which the outer edge of the tool rotates in relation to the material being cut. In general, the SFM is within a range based upon the workpiece material, its condition, hardness and depth of the hole. The deeper the hole, the greater tendency for more heat to be generated. Speed reduction is often recommended to minimize the amount of heat. It is usually best to start drilling at a slower speed and then increase. Split Point A special point confi guration that eliminates walking so holes stay on center Web The central portion of the body that joins the lands. The extreme end of the web forms the chisel edge of a two-fl ute drill Web Thickness The thickness of the web at the point, unless otherwise specifi ed 53 GENERAL TOOL INFORMATION

54 Drill Surface Treatments Black Oxide Black oxide is the most basic surface treatment recommended for drilling in iron and steel. It is not recommended for drilling in aluminum, magnesium or similar materials. Drilling with a black oxide treated drill provides: Increased tempering and stress relieving Reduced galling and chip welding Increased retention of lubricants TiN Coating Titanium Nitride (TiN) performance coating can increase tool life and productivity by allowing higher speeds and heavier feeds. It is an excellent general purpose coating for protecting tools from wear. TiN coating is an excellent choice for drilling in iron and steel. It is also recommended for drilling in aluminum, magnesium or similar materials. Drilling with a TiN coated drill provides: Increased surface hardness Reduced coeffi cient of friction Increased corrosion resistance A thermal barrier Additional tempering and stress relieving Surface Feet per Minute 10' 12' 15' 20' 25' 30' 35' 40' 45' 50' 60' 70' 80' 90' 100' Diameter Size Revolutions per Minute 1/ / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / GENERAL TOOL INFORMATION 54 Material SFM Aluminum and its Alloys Brass and Bronze (Ordinary) Bronze (High Tensile) Die Castings (Zinc Base) Iron Cast (Soft) Cast (Medium hard) Hard Chilled Malleable Magnesium and its Alloys Monel Metal or High-Nickel Steel Plastics or Similar Materials (Bakelite) Steel Mild (.2 carbon to.3 carbon) Material SFM Steel (Continued) Steel (.4 carbon to.5 carbon) Tool (1.2 carbon) Forgings Alloy 300 to 400 Brinell High Tensile (Heat Treated) 35 to 40 Rockwell C to 45 Rockwell C to 50 Rockwell C to 55 Rockwell C 7 15 Stainless Steel Free Machining Grades Work Hardening Grades Wood Drill Dia.

57 Common Tapping Terms Chamfer Styles in Standard Taps End Views Angle of Thread The angle included between the fl anks of the thread measured in an axial plane Back Taper A slight axial relief on the thread of the tap which makes the pitch diameter of the thread near the shank somewhat smaller than that of the chamfered end Bottoming Chamfer The shortest chamfer (1-2 threads long) for threading close to the bottom of blind holes Chamfer The tapering of the threads at the front end of each land of a tap, by cutting away and relieving the crest of the fi rst few teeth, to distribute the cutting action over several teeth Chamfer Relief The gradual decrease in land height from cutting edge to heel on the chamfered portion, to provide clearance for the cutting action as the tap advances Chordal Hook Angle The angle between the chord passing through the root and crest of a thread form at the cutting face, and a radial line through the crest at the cutting edge Crest The top surface joining the two fl anks of a thread. The crest of an external thread is at its major diameter, while the crest of an internal thread is at its minor diameter Cutting Face The leading side of the land in the direction of rotation for cutting on which the chip impinges Flutes The longitudinal channels formed in a tap to create cutting edges on the thread profi le, and to provide chip spaces and cutting fl uid passages Height of Thread The distance between the crest and the base of a thread measured normal to the axis Lead The distance a screw thread advances axially in one complete turn. On a single lead screw or tap, the lead and pitch are identical. On a double-lead screw or tap, the lead is twice the pitch, etc. Pitch The distance from any point on a screw or tap thread to a corresponding point on the next thread, measured parallel to the axis. The pitch equals one divided by the number of threads per inch Pitch Diameter On a straight thread, the diameter of any imaginary coaxial cylinder, the surface of which would pass through the thread profi le at such points as to make equal the width of the threads and the width of the spaces cut by the surface of the cylinder On a taper thread, the diameter at a given distance from a reference plane perpendicular to the axis of an imaginary co-axial cone, the surface of which would pass through the thread profi le at such points as to make equal the width of the threads and the width of the spaces cut by the surface of the cone Plug Chamfer The most common chamfer (3-5 threads long), for hand or machine tapping in through or blind holes Rake Any deviation of a straight cutting face of the tooth from a radial line. Positive Rake means that the crest of the cutting face is angularly advanced ahead of the balance of the face of the tooth. Negative Rake means that the same point is angularly behind the balance of the cutting face of the tooth. Zero Rake means that the cutting face is directly on the center line Spiral Point (Chip Driver) A supplementary angular fl uting cut in the cutting face of the land at the chamfer end. It is slightly longer than the chamfer on the tap, and of the opposite hand to that of rotation Taper Chamfer A long chamfer (8-10 threads long) for easier starting and engagement in the work piece. More working teeth means that less tapping torque is required, and the chip load is reduced on each tooth Threads Per Inch The number of threads in one inch of length 57 GENERAL TOOL INFORMATION

The optimum speed for tapping is the highest speed that conditions permit, consistent with acceptable tool life. Speeds must be lowered as the length of the hole increases. In short holes, taps with tapered chamfers can be operated faster than taps with bottoming chamfers. Speeds can be increased when vertical tapping, as compared to horizontal tapping.
