Precision Twist Drill 040816 Hss Stub Drill 1/4 in

Product Description

The PRECISION TWIST DRILL 040816 is a high-speed steel (HSS) stub-length drill bit designed for heavy-duty material removal where rigidity and accuracy are priorities. The stub body keeps the overall flute length short, reducing deflection and flex during drilling operations. This bit has a 1/4 inch diameter tip and a 2.5 inch depth of cut. The shorter geometry stiffens the drill along its axis, making it well suited for applications where a standard-length bit would walk, chatter, or drift. Machinists, maintenance technicians, and metal fabricators reach for stub drills when hole placement accuracy matters more than depth capacity.

This stub-length HSS drill bit is used in machine shops, industrial maintenance environments, and fabrication operations. Its rigid body makes it a practical choice for drilling through steel, cast iron, aluminum, and similar materials on drill presses, milling machines, and hand-held power drills. The short flute design also performs well when working in confined spaces or close to a workpiece edge where a jobber-length bit would not seat properly in the chuck before contact.

Key Features

• Stub-length body reduces flex and deflection for improved hole accuracy
• High-speed steel (HSS) construction provides hardness and heat resistance for metal drilling
• 1/4 inch diameter cutting tip
• 2.5 inch depth of cut supports a wide range of general drilling tasks
• Short flute length increases rigidity compared to jobber or aircraft-length alternatives

Compatibility

Designed as an OEM-style replacement or standard substitute for 1/4 inch HSS stub-length drill bits used in industrial and maintenance drilling applications.

Installation Notes

Installation of this drill bit is performed by machinists and maintenance technicians using a compatible drill press, milling machine, or hand-held power drill with the appropriate chuck size. Secure the bit firmly in the chuck before operation and verify the workpiece is clamped or fixtured to prevent movement. Wear appropriate eye protection and follow shop safety protocols when drilling metal. Inspect the cutting edges for wear or damage before each use.
