Dewalt Accessories DWA1211 Cobalt Drill Bit 11/64 in 5 Pack

Product Description

The DEWALT ACCESSORIES DWA1211 is an 11/64 inch cobalt alloy steel drill bit engineered for high-speed drilling in tough materials including stainless steel, heavy steel, and hardwood. Sold in a 5-piece pack, each bit features a split point tip that starts cutting on contact, eliminating bit walking and improving hole placement accuracy. The cobalt construction delivers up to four times the service life compared to standard black oxide bits, making this set a practical choice for licensed tradespeople and experienced DIYers who regularly drill through ferrous metals and structural steel.

This bit is suited for metalworking and general-purpose drilling applications across residential and commercial job sites. The 11/64 inch diameter is commonly used for pilot holes, fastener clearance holes, and precision drilling in sheet metal, I-beams, angle iron, and dense wood stock. HVAC technicians, electricians, plumbers, and ironworkers who frequently penetrate steel enclosures or structural members will find the cobalt formulation particularly useful for extended production drilling without frequent bit replacement.

Installation Notes

Installation of this bit is performed by licensed tradespeople or qualified DIYers using a standard drill driver or drill press. Secure the bit fully in the chuck before operation and verify chuck tightness to prevent slippage. When drilling stainless or heavy steel, apply cutting oil to reduce heat buildup and extend bit life. Always wear appropriate PPE including eye protection when drilling metal.
