Product Description

The PRECISION TWIST DRILL 5995547 is a 20-piece jobber length drill bit set in wire gauge sizes, designed for metalworking and general-purpose drilling applications. All 20 bits are manufactured from high speed steel with a bright, uncoated finish and feature a standard 118-degree split point for reliable starting on ferrous and non-ferrous materials. Straight shanks ensure compatibility with standard drill chucks. The set covers wire gauge sizes from No. 80 through No. 61, making it a practical reference range for technicians who need precision clearance and tap-size holes in the field or shop.

This set is suited for metalworking professionals, HVAC technicians, plumbers, electricians, and maintenance trades who regularly drill clearance holes, pilot holes, or tap-size holes in sheet metal, mild steel, and similar materials. The jobber length format provides a balance of reach and rigidity appropriate for handheld drills and drill presses. Bits conform to ANSI specifications and are packaged in a metal storage case that keeps the set organized on a job site or service vehicle. The R18P series designation identifies the product line within PRECISION TWIST DRILL's standard inch-measurement catalog.

Installation Notes

Installation is performed by the end user or a qualified trades professional using standard drill equipment. Secure the workpiece before drilling and use appropriate cutting fluid when drilling harder metals to extend bit life. Ensure the drill chuck is tightened fully before operation to prevent bit slippage. Inspect bits for wear or damage before each use and replace individual bits that show signs of chipping or dulling.
