Precision Twist Drill 010229 Hss Drill Bit 29/64 in R10B 6 Pack

Product Description

The PRECISION TWIST DRILL 010229 is a high speed steel (HSS) drill bit designed for professional drilling applications in metal, wood, and general-purpose materials. Built to the R10B style with a 135-degree split point geometry, this bit delivers fast penetration and self-centering performance without the need for a center punch. The black oxide finish reduces friction and provides light corrosion resistance during use. At 29/64 inches in diameter, this bit is sized for larger-bore drilling tasks commonly encountered by machinists, pipefitters, electricians, and maintenance technicians.

This drill bit is suited for use in production and job-site environments where consistent performance across multiple holes is required. The 135-degree split point reduces walking on hard or smooth surfaces, making it a practical choice when drilling into steel plate, structural members, or other hard stock. Sold in a pack of 6, it supports shop inventory needs and reduces downtime from bit replacement. It is appropriate for use with standard drill presses, magnetic drills, and heavy-duty hand drills capable of driving larger-diameter bits.
