Disston Company 295170 Titanium Hss Drill Bit 1/2x6 in

Product Description

The DISSTON COMPANY 295170 is a titanium-nitride coated high-speed steel (HSS) drill bit designed for heavy-duty drilling across a wide range of materials. Measuring 1/2 inch in diameter and 6 inches in length with a 3/8-inch shank, this jobber-length bit features a 135-degree split point with four cutting edges. The split point geometry eliminates bit walking on contact, allowing for quick, accurate hole starting without a center punch. The titanium-nitride surface finish adds lubricity that improves chip flow, reduces heat buildup, and extends overall bit life compared to uncoated HSS bits.

This bit is suited for heavy-duty drilling in wood, plastic, wallboard, and plywood, as well as soft metals. It also handles moderate use in heat-treated or ferrous metals. Typical installers include electricians, plumbers, HVAC technicians, and general contractors who need a reliable multipurpose bit for both rough-in work and finish drilling. The 3/8-inch shank fits standard 3/8-inch and 1/2-inch chucks, making it compatible with most corded and cordless drills used in the trades.

Installation Notes

Installation of this bit is performed by electricians, plumbers, HVAC technicians, and general tradespeople during rough-in or structural drilling. Secure the 3/8-inch shank firmly in the chuck before use and verify the chuck is fully tightened. When drilling metal, use appropriate cutting fluid to manage heat and extend bit life. Reduce feed pressure when breaking through the back side of a workpiece to prevent grabbing or bit damage.
