Boron Killer® Drill Bit Р6.7 x 80mm

Description

• The ONLY way to drill through Boron Steel is with this bit.
• This drill bit was created to specifically cut spot welds from Boron Steel.
• Made of Tungsten Carbide this 8.0 mm, special multi-layered coated, 3-fluted drill bit is the only bit that is tough enough to drill through and survive Ultra High Strength Steel, aka Boron Steel.
• The three cutting edges help spread cutting forces over a greater area, thus helping prevent premature breakage.
• When used with the 1800 rpm drill it is suggested that air flow be restricted slightly to decrease rpm.
• We do not recommend this bit be used with drills without low RPM's or that are not adjustable; optimum RPM is 1000.
• The drill bit, being made of Carbide, is sensitive to incorrect pressures applied by these copies and thus subject to immediate breakage.
