Value Collection 01358290 Size 29 Screw Machine Drill Bit Hss

Product Description

The VALUE COLLECTION 01358290 is a screw machine length (stub-length) drill bit designed for high-volume, close-tolerance drilling in metal, wood, and plastic. Built from high-speed steel (HSS) with an oxide finish for basic lubricity and corrosion resistance, this bit cuts a 0.1360-inch diameter hole corresponding to wire gauge size 29. The 118-degree standard point angle suits general-purpose work across a wide range of workpiece materials. At 1-15/16 inches overall length, the stub format provides added rigidity compared to jobber-length bits, reducing deflection in short-reach drilling applications. Installation and use require standard drill chucks accepting a straight cylindrical shank. Machinists, toolmakers, and maintenance technicians are the primary users.

This bit is suited for bench drilling, drill press, and CNC or turret applications where a rigid, short-length tool is preferred. The regular spiral flute and parallel web configuration support efficient chip evacuation in typical through-hole and blind-hole work. The web-thinned point reduces thrust force at drill entry, which is useful when working with thinner stock or when minimizing workpiece distortion matters. Right-hand cutting direction is standard for conventional drill setups. No coolant-through capability is present, so external cutting fluid should be applied when drilling harder alloys or high-volume runs to extend tool life.

Key Features

• Size 29 wire gauge diameter: 0.1360 inches for precise, repeatable hole sizing
• High-speed steel construction with oxide coating for general-purpose durability
• 118-degree standard point angle for broad material compatibility
• Stub screw machine length (1-15/16 inches OAL) provides rigidity and reduces deflection
• Web-thinned point reduces entry thrust and improves hole-start accuracy
• 2-flute regular spiral design promotes consistent chip clearance

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with any drill press, bench drill, or CNC setup accepting a straight cylindrical shank. Suitable for drilling steel, aluminum, brass, plastics, and wood where a size 29 wire gauge hole diameter is required.

Installation Notes

Secure the straight shank firmly in a drill chuck, collet, or toolholder before use and confirm runout is within acceptable limits for the application. Power down the machine completely before changing or inspecting bits. Apply cutting fluid externally when drilling harder metals or running extended production cycles to reduce heat buildup and extend bit life. Do not exceed the recommended feed and speed parameters for HSS tooling in the workpiece material being drilled.
