Precision Twist Drill 010018 Hss Jobber Drill Bit 9/32 in

Product Description

The PRECISION TWIST DRILL 010018 is a high-speed steel jobber-length drill bit built for demanding applications on hard surfaces. With a 9/32-inch tip diameter and a 4-inch depth of cut, this bit handles the heat and force common in metal fabrication, mechanical assembly, and general trade work. The overall length is 4-1/4 inches, keeping it compact enough for standard drill presses and hand drills alike. High-speed steel construction maintains cutting edge integrity under elevated temperatures where carbon steel bits would soften and fail. This is a workhorse bit suited for tradespeople who drill frequently into steel, cast iron, and similar hard materials.

This jobber-length bit is a standard choice for HVAC technicians, plumbers, electricians, and fabricators who need consistent, clean holes in metal components. The 9/32-inch diameter is a commonly called-for size for pilot holes, conduit knockouts, fastener clearance, and bracket mounting across residential and light commercial applications. Its compact length allows use in tight spaces where longer bits are impractical.

Key Features

• High-speed steel construction resists heat buildup during aggressive drilling
• 9/32-inch diameter covers common fastener and conduit clearance applications
• 4-inch depth of cut accommodates standard material thicknesses
• Jobber-length design balances reach and rigidity for accurate drilling
• 4-1/4-inch overall length fits standard drill chucks and press setups

Compatibility

Designed as a standard jobber-length replacement or stock bit compatible with any 3/8-inch or larger keyed or keyless drill chuck accepting round-shank bits in the 9/32-inch diameter range.

Installation Notes

Always secure the workpiece before drilling to prevent rotation and injury. Use cutting fluid or oil when drilling hard metals to extend bit life and reduce heat buildup. Inspect the cutting edge before each use and replace bits that show chipping or significant wear. Proper speed selection for the material and diameter is critical — consult a speeds-and-feeds reference for the material being drilled.
