Precision Twist Drill 010217 Hss Drill Bit 1/4 Inch 12 Pack

Product Description

The PRECISION TWIST DRILL 010217 is a 1/4-inch high speed steel (HSS) drill bit designed for reliable performance in metal, wood, and general-purpose drilling applications. Built to the R10B style with a 135-degree split point geometry, this bit starts on contact without center-punching and cuts cleanly through a wide range of materials. The black oxide finish reduces friction and provides light corrosion resistance during normal shop use. This bit ships in a pack of 12, making it a practical choice for contractors, maintenance trades, and service technicians who burn through tooling regularly.

The 010217 is suited for use in hand-held drills and drill presses across residential and light commercial job sites. The 135-degree split point tip is well regarded in metal drilling applications where bit walking is a concern. The 1/4-inch diameter is a common size for pilot holes, fastener clearance, and electrical and plumbing rough-in work. Supplied in a 12-pack format, this SKU fits tool crib and service van replenishment purchasing patterns.

Installation Notes

Install and remove drill bits only with the tool unpowered and the chuck fully released. Secure the workpiece firmly before drilling to prevent rotation. Use cutting fluid or lubricant when drilling hardened metals to extend bit life and reduce heat buildup. Inspect the cutting edges for wear before each use and replace bits that show chipping or significant dulling.
