135° HRA.89 YG6 Solid Carbide Stub Length Twist Drills Bit Jobber Drill
Bit Precision Ground Hardplate For ALL STEEL Stainless Steel Metal
Stub Length
Stub length (aka Mechanics length): Shorter than jobber drills, mechanics length drills are named as such because they fit into tighter spaces and are less likely to break while still allowing a reasonable flute length.
YG6 Solid Carbide
YG6 Solid Carbide (aka ISO K20), which density is about 14.5-14.9 g/cm3. The hardness of it is about 89HRA.
The bending strength of it is 1380N/cm2 and the the impact toughness is about 2.5J/cm2.It is harder, tougher, and more resistant to extreme loads, which is specially designed to cut ALL STEEL.
No Center Punch Need
The 135° Quick-Cut points are self-centering and penetrate quickly with less pressure.
Will not "walk" or "wander". Straight shank allows for firmly holding and accurate centering, fit for standard drill chucks and regular round collet chucks.
Must be used and operated at proper RPMs for maximum efficiency.
