Precision Twist Drill 010230 Hss Drill Bit 15/32 in R10B 6-pack

Product Description

The PRECISION TWIST DRILL 010230 is a high speed steel (HSS) drill bit engineered for demanding metal drilling applications. Finished in black oxide, this bit follows the R10B style and features a 135-degree split point geometry that reduces walking on contact, allowing it to start cutting immediately without a center punch. At 15/32 inches in diameter, it is sized for through-holes and clearance holes commonly encountered in structural, fabrication, and mechanical service work. Each pack contains 6 bits, making it a practical stock item for shop or field use. HSS construction provides good wear resistance across a range of ferrous and non-ferrous workpieces.

This drill bit is suited for use in general metalworking, HVAC equipment fabrication, electrical panel work, and plumbing rough-in tasks where precise, clean holes are required in steel, aluminum, copper, or similar materials. The 15/32-inch size is frequently used for bolt clearance and conduit knockout applications. The 6-pack format supports high-volume production environments and service fleets that cycle through tooling regularly.

Key Features

• 135-degree split point reduces walking and eliminates the need for a center punch on most surfaces
• High speed steel (HSS) construction withstands heat generated during sustained metal drilling
• Black oxide finish provides light corrosion resistance and reduced friction during cutting
• R10B style geometry designed for general-purpose Type B drilling applications
• 15/32-inch diameter suits bolt clearance and conduit knockout work
• Sold in a pack of 6 for consistent tooling inventory on busy job sites or in production shops

Compatibility

Designed as a general-purpose OEM-style HSS drill bit compatible with standard 3-jaw drill chucks and keyed chuck systems accepting 15/32-inch shank diameters, including corded and pneumatic drill presses and hand drills commonly used in trade applications.

Installation Notes

Installation of this drill bit is performed by licensed or qualified tradespeople including HVAC technicians, electricians, and plumbers using standard drill press or hand drill equipment. Secure the bit fully in the chuck and verify it is centered before applying power. Wear appropriate eye protection and secure workpieces firmly before drilling. Follow applicable OSHA and workplace safety standards when operating rotary cutting tools.
