Precision Twist Drill 010226 Hss Drill Bit 13/32 in R10B 6 Pack

Product Description

The PRECISION TWIST DRILL 010226 is a high speed steel (HSS) drill bit engineered for demanding metal drilling applications. Built to the R10B style and PTD JL 135SP Type B specification, this bit features a 135-degree split point geometry that reduces walking on contact and requires no center punch on most surfaces. The black oxide finish provides light corrosion resistance and helps reduce friction during cutting. At 13/32 inches in diameter, this bit is well suited for bolt clearance holes, stepped hole prep, and general fabrication work. Each pack contains 6 bits, making it a practical choice for shops and service trucks that need a reliable supply on hand.

This drill bit is intended for use in metal fabrication, mechanical contracting, HVAC rough-in, and general trade work where consistent hole geometry and tool life matter. The 135-degree split point tip is particularly effective on hard metals and stainless where standard 118-degree bits tend to wander or require excessive feed pressure. Machinists, pipefitters, sheet metal workers, and general tradespeople are the primary installers and users of this bit size and style.

Key Features

• High speed steel (HSS) construction for durability across ferrous and non-ferrous metals
• 135-degree split point tip reduces bit walking and eliminates the need for center punching on most work
• R10B style geometry provides consistent chip evacuation and cutting efficiency
• Black oxide finish reduces friction and provides light corrosion resistance
• 13/32-inch diameter suited for bolt clearance and fabrication hole prep
• 6 bits per pack for extended jobsite or shop availability

Compatibility

Designed as an OEM-style replacement and standard trade bit for use in 3/8-inch and 1/2-inch keyed or keyless drill chucks that accept 13/32-inch shank diameters, including benchtop drill presses and handheld power drills commonly used in metal fabrication and mechanical contracting.

Installation Notes

Secure the bit fully in the chuck before operation and verify the chuck key is removed before starting the drill. Use appropriate cutting fluid or lubricant when drilling hard metals to extend bit life and maintain hole accuracy. Ensure the workpiece is clamped securely to prevent rotation. Worn or damaged bits should be replaced rather than reground in the field without proper equipment.
