3 Flute Solid Carbide Drills

1 3 flute drill, drilling a pre-hole 2 Gundrill penetration

(drill diameter +0.02 mm) through the pre-hole

2 x D min

• The solid carbide drills can be re-sharpened and re-coated cutting edge and gash geometry, producing an at least 10 times (see re-grinding instructions on page optimal chip on all kinds of materials, providing 595). excellent chip evacuation.
• The 3 flute drills feature high dynamic stability and reduced
• Excellent performance on low carbon steel or other

vibrations, which enable high speed drilling on nonferrous gummy materials, when compared to any other 3 flute materials. (It is recommended to use balanceable adapters solid carbide drills which are usually not recommended when exceeding 10,000 RPM). to be used on such materials.

• 3 flute, solid carbide drills can be used with minimal
• Higher cutting edge life, when compared to 2 flute solid

quantity lubrication or emulsion spray (MMS or MQL carbide drills without internal coolant holes. systems) or even dry machining for nonferrous materials. (The load is divided among three cutting edges,

• The 3 flute solid carbide drill has a unique versus two).

When compared to 2 flute solid carbide drills:

• Prolonged cutting edge life increases productivity, due to decrease in drill change and setup time.

Primary Less torque per cutting edge, therefore, can be used at Clearance Wiper higher feed rates or used to reduce torque on machines Chisel with limited torque Gash Secondary The 3 flute solid carbide drills can be used on any CNC Cutting Lip machining center, lathe machine, or drilling machine Primary Cutting Lip (which usually provides better and more stable conditions).
