Precision Twist Drill 040824 Hss Stub Drill 3/8 in

Product Description

The PRECISION TWIST DRILL 040824 is a high-speed steel (HSS) stub-length drill bit designed for applications requiring extra rigidity and drilling accuracy. With a 3/8 inch diameter tip and 2.5 inches of cutting depth, this stub drill features a shorter-than-standard body and flute length that minimizes deflection and chatter during use. The reduced overall length of 3-1/8 inches makes it well-suited for confined spaces and close-tolerance work where a jobber-length bit would be impractical. Licensed tradespeople and machinists rely on this geometry when straightness and hole accuracy are critical.

This stub drill is appropriate for use in metalworking and general fabrication environments, including HVAC, plumbing, and electrical rough-in work where drilling through steel framing, brackets, or equipment panels is required. The heavy-duty construction and short flute design allow it to maintain rigidity even under aggressive feed rates, making it a practical choice for production drilling or repetitive hole-making tasks in ferrous and non-ferrous metals.

Key Features

• Short stub-length body reduces deflection for improved hole accuracy
• High-speed steel (HSS) construction for durability in metal drilling applications
• 3/8 inch diameter tip suits common fastener and anchor hole sizes
• 2.5 inch depth of cut handles standard-depth through-holes in structural members
• Compact 3-1/8 inch overall length fits tight clearance drilling situations

Compatibility

Designed as a standard stub-length drill bit compatible with 3/8 inch keyed or keyless drill chucks and compatible benchtop drill presses, hand drills, and magnetic drill setups accepting 3/8 inch shank tooling.

Installation Notes

Installation is performed by tradespeople using standard drill equipment; always secure the workpiece before drilling to prevent rotation. Ensure the drill chuck is tightened fully and the bit is seated squarely before applying feed pressure. Use appropriate cutting fluid when drilling hardened or thick steel to extend bit life and maintain hole quality. Disconnect power to any drill press before changing bits.
