Precision Twist Drill 5995528 Drill Bit Set 15 Pc

Product Description

The PRECISION TWIST DRILL 5995528 is a 15-piece jobber length drill bit set made from high speed steel, designed for general-purpose metalworking and multipurpose drilling applications. The set covers a size range from 1/16 inch to 1/2 inch in 1/32-inch step increments, giving technicians a practical spread of common hole sizes in a single indexed case. All bits feature a standard 118-degree point angle and a straight shank, both of which are compatible with standard drill chucks. The bright, uncoated finish is suitable for use in a wide range of base materials without the constraints of coated-bit handling requirements. This set meets ANSI specification standards.

This set is well-suited for HVAC technicians, plumbers, electricians, and general maintenance professionals who require a reliable range of drill sizes for everyday trade work. Typical applications include drilling pilot holes, clearance holes, and mounting holes in sheet metal, mild steel, aluminum, plastic, and similar materials. The plastic storage case keeps bits organized and indexed for quick size selection on the job site or in the shop. The jobber length geometry provides a balance of reach and rigidity appropriate for hand-held and bench-mounted drilling operations.

Installation Notes

Secure the bit firmly in the drill chuck before operation and verify chuck key is removed before powering the drill. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and improve hole quality. Always wear appropriate eye protection and secure workpieces properly before drilling. Inspect bits for wear or damage before each use and replace any bit that shows signs of chipping or heat discoloration.
