Precision Twist Drill 010227 Hss Drill Bit 27/64 Inch 6 Pack

Product Description

The PRECISION TWIST DRILL 010227 is a high speed steel (HSS) drill bit designed for reliable performance in metal, wood, and general-purpose drilling applications. Offered in a 6-per-pack configuration, this bit carries the R10B style designation and is manufactured to the PTD JL 135SP Type B specification. The 135-degree split-point geometry reduces walking at the start of a cut and allows drilling without a center punch in most applications. The black oxide finish provides a base level of corrosion resistance and reduces friction during cutting. At 27/64 inch in diameter, this bit fills a common need in mechanical and fabrication work.

This drill bit is suited for trade professionals working in HVAC, plumbing, electrical, and general mechanical fabrication where precise, clean holes are required. The 27/64 inch size is commonly used for tapping operations and clearance holes in light-gauge steel, aluminum, and similar materials. The 6-pack format makes it practical for service vans and shop environments where bit replacement is routine. Licensed tradespeople and skilled DIYers who work with ferrous and non-ferrous metals will find this a straightforward, dependable option.
