Precision Twist Drill 040810 Hss Stub Drill 5/32 in

Product Description

The PRECISION TWIST DRILL 040810 is a high-speed steel (HSS) stub-length drill bit designed for applications where rigidity and drilling accuracy are critical. With a 5/32-inch diameter tip and a 2.5-inch depth of cut, this stub drill delivers controlled, precise holes in metal, wood, and composite materials. The shortened flute and overall body length reduce lateral flex during drilling, making it a reliable choice for production environments and fieldwork where straight, clean holes are required. Licensed tradespeople and fabricators working on tight-tolerance applications reach for stub-length geometry when standard jobber-length bits introduce too much deflection.

This stub drill is suited for use in drill presses, hand drills, and CNC setups where a compact cutting tool is needed in confined spaces or where a shorter bit column reduces chatter. It is commonly used in mechanical, HVAC, plumbing, and electrical trade work for sheet metal penetrations, joist drilling, and panel fabrication. The 5/32-inch diameter makes it a common size for pilot holes, screw clearance, and rivet preparation across a wide range of light-gauge and structural materials.

Key Features

• HSS construction provides hardness and heat resistance for drilling metal and other hard materials
• Stub length geometry reduces bit flex for greater drilling accuracy and straighter holes
• 2.5-inch depth of cut handles most standard penetration tasks without repositioning
• 5/32-inch diameter covers common pilot hole and fastener clearance applications
• Short flute design minimizes deflection in production and repetitive drilling scenarios

Compatibility

Designed as a standard stub-length HSS drill bit compatible with 3-jaw chucks and quick-change drill systems that accept 5/32-inch shank tooling.

Installation Notes

Installation of this drill bit should be performed by a qualified technician familiar with rotary cutting tools and appropriate personal protective equipment including eye and hand protection. Secure the bit fully in the chuck and verify concentricity before drilling to prevent premature tip wear or breakage. Use cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain dimensional accuracy. Disconnect or de-energize equipment before drilling into panels or enclosures containing live electrical components.
