Product Description The BOSCH line of countersinks are great for deburring and chamfering openings to pre-drilled holes. Great for electrical, plumbing and HVAC contractors. BOSCH countersinks cut varied materials cleanly and accurately. With standard high-speed steel and super hard titanium-coated bits, these countersinks perform great in even the toughest materials. From the Manufacturer Bosch titanium screwdriver bits feature patented Titanium Tough Grip coating. These innovative bits start with a rough surface that actually grips the entire inside dimension of the screw head with millions of gripping points. The bits are then coated with titanium to provide a hard surface that protects the gripping points from the rigors of repetitive use. Titanium Tough Grip coating significantly reduces slippage with 75 percent more gripping power and protects each gripping point from damage so bits don't need to be replaced as often as standard screwdriver bits. The power groove on each bit fits all quick change systems and can be chucked directly into a drill.
