Sharp cutting edge performance and smooth chip discharge B26A Solid carbide 5XD DRILL Superior design wavy cutting edge & flute geometry Sharp cutting edge performance and smooth chip discharge. Miracle Coated VP15TF Miracle coating displays high welding resistance therefore it can be used for machining a wide range of workpiece materials such as Plain steels, Mild steels, Carbon steels,stainless steels and Cast iron.

Flute geometry Cross sectional shape Greatly improved chip disposal due to the small "R" design to curl generated chips small and large the large "R" design to promote smooth chip evacuation.

2 Solid carbide Features Undulating cutting edge & special flute geometry promotes smooth chip evacuation. Cutting edge shape 5 X D DRILL Undulating cutting edge Hollows engineered into the cutting edge produces sharp cutting performance, bumps achieve a strong cutting edge at the same time. Flute geometry Cross sectional shape Greatly improved chip disposal due to the small "R" design to curl generated chips small and large the large "R" design to promote smooth chip evacuation. Large R part Small R part Cutting resistance & chip geometry lowers cutting resistance and power consumption therefore exhibiting excellent chip disposal with compact chip discharge.

Runout.1inch Coolant method (MWS) Small diameter application Thin workpieces Interrupted cutting Spindle through coolant type Revolving coolant machine type One process 1D1 If bending occures Lower feed when ing interrupted part. Coolant pressure is approx..5-1mpa (Ø5 : 2-3MPa). Coolant volume is l/min. When machining a prepared hole with the MICRO-MZE or other center s, set the depth to 1D1 (D1 = Diameter). Use the prepared hole as a guide when machining with the desirable with an oil hole. Depending on the cutting conditions, step feed ing is recommended. Support the workpiece Requires prior ing Spot face with an end mill prior to ing. Stepped holes Divide the machining into two processes. Drill the larger hole first. *Tools for chamfering and spot facing can be produced to order. Burring and workpiece chipping Lower the feed rate at the end of through cutting. Add a chamfer. Change the point angle. Caution in using the MWS type (Drill diameter Ø.118) Please use a fine mesh filter (mesh 3µm) for coolant to prevent jamming in the oil hole. For deep ing (l/d 3), machining guiding hole is recommended. (Use MICRO-MZE type for guiding hole.) Step ing is also effective. Coolant handling < MWS type > 1) Dirt and dust particles in old coolant adhere to the oil hole and prevent effective flow. Regular coolant exchange is recommended. 2) Small particles of swarf will jam in the oil hole. Always use a filter as a preventative measure. When using small diameter s, use a fine mesh filter. 6
