BORDO Panel Drills HSS Black Single Ended
- 135° Split Point (crankshaft point)
- Split point is self centering reducing the need for end thrust.
- The 135° point provides superior performance when drilling harder steel materials.
- In most situations it will produce thicker chips minimising work hardening of the cavity.
- Faster penetration reduces abrasion and friction along the cutting edges.
- Black Finish Drills (also called blue finish) achieve their distinctive colour by steam tempering, a thermal process resulting in a porous tool coating.
- This surface helps to keep lubricant on the tool, particularly important on the cutting edges, thus reducing friction and cold welding.
- The result is increased tool life.
- Black finish tools are generally recommended for ferrous applications where the oxide layer aids chip flow and heat dissipation.
