2 Making Holes is not new. We have been making holes since early man primarily for the purpose of assembly (put things together). Some of the first holes using tools to create mechanical advantage were the Egyptians utilizing a hollow core bow saw.

3 35,000 BC History of changes with Drilling 10,000 BC 3,000 BC Pump Drill - Romans 1,300 AD 1,500 AD Strap Drill Core Drill - Egyptians Use of Shells & Bone Hollow Bore Tip (Copper) Trepanning Auger, Rotating Helical Screw

4 1835 AD History of changes with Drilling 1889 AD Electric Motor Drill Drill Press with wind, water or human powered Metal Bits HSS Brazed Carbide Solid Carbide Indexable Carbide Material & Geometry Science

5 (FLAT, GROUND) Original drills based on turning inserts History of changes with Drilling Pressed inserts designed for drilling as a specific application Indexable Carbide Inserts created to replicate SCD Sumo ICG, Flat, HCP Molding science to improve upon grinding geometry Pressing technology enables more range WOLH Chamdrill

6 The time and cost to produce a precision hole is amazingly quick. The materials cut are also much more difficult to cut

7 Adoption of Indexable Drilling Head technology to improve drilling productivity 3 major areas of consideration 1) Ancillary cost reduction 2) Error reduction through simplification 3) Available technology range and advantages

8 Adoption of Indexable Drilling Head technology to improve drilling productivity 1) Ancillary cost reduction Eliminate regrinding cost and inconsistency in tool life Variation Inconsistent Performance Decreased Tool Life

9 Variation means additional steps in your process to manage it Eliminate Variation Reduce Probability of Error

10 Adoption of Indexable Drilling Head technology to improve drilling productivity 1) Ancillary cost reduction Reduce inventory mgmt Eliminate regrinding cost and inconsistency in tool life Reduce Space Reduce # of Items

11 Adoption of Indexable Drilling Head technology to improve drilling productivity 1) Ancillary cost reduction One Reduce drill inventory body can mgmt support many insert diameters Range

12 Adoption of Indexable Drilling Head technology to improve drilling productivity 2) Error Reduction through Simplification Uninstall Ship Recondition Ship

13 Error Reduction through Simplification Measure Install Input

14 Indexable Technology Reduces Chance of Error Install Uninstall Install Repeatability of +/-.001

15 Adoption of Indexable Drilling Head technology to improve drilling productivity 3) Technology Range and Advantages - Range of diameters and length of diameters - Special geometries for problem solving - Advantage of steel body vs solid carbide drill

16 Range of diameters and length of diameters Small Diameters (4mm) Complex Multi-Operation Options to go Deep

17 Special geometries for problem solving Special geometries for problem solving & high performance

18 Special geometries for problem solving Resolve Stability issue with long extension ratios Vibration

19 Special geometries for problem solving Chip evacuation issues due to material or machine limitations

20 Advantage of steel body vs solid carbide drill Steel bodies allow for drilling a range of sizes or boring by offsets Steel bodies allow for deflection to compensate for machine misalignment or non-flat surfaces Steel bodies do not require length measurements and offsets when indexing inserts

21 Adoption of Indexable Drilling Head technology to improve drilling productivity Summary 1)Ancillary Cost reduction 2) Error reduction through simplification 3) Technology Range and Special Advantages of Technology
