Solid carbide drills — WhizDrill
Carbide 1-flute twist drill with reinforced shank | Style A
The large flute gives plenty of room for chip evacuation. Suitable for titanium, and other hard materials.
Carbide 2-flute twist drills with reinforced shank | Style B
Good overall drill. Type that depends more on the application than the actual material. Suitable for most materials.
Carbide 2-flute self centering twist drill with reinforced shank | Style BA
Good overall drill. Type that depends more on the application than the actual material. Suitable for most materials. Style BA to be used when high heat is generated or better chip evacuation is needed. Style BA reamer can be eliminated and hole positioning is increased.
Carbide 2-flute coolant through twist drill with reinforced shank | Style BC
Good overall drill. Type that depends more on the application than the actual material. Suitable for most materials.
Carbide 3-flute twist drill with reinforced shank | Style C
Drills to tight tolerances so reamer can be taken away.
Most often no centre drill needed.
To be used in tough stainless steel, medical steels like 316 and MP35.
Carbide 2-flute multiple step twist drill with reinforced shank | Style E
Special applications where the cycle time, hole quality and concentricity is a priority.
For most materials.
Carbide spade drill | Style F
Often used in watchmaking.
For softer materials, short holes.
Carbide centre drills | Style G
A big benefit of choosing helix and point angle per application.
Centre drills suitable for all materials.
Carbide centre drills long | Style H
A big benefit of choosing helix and point angle per application.
Centre drills suitable for all materials.
