Value Collection 01293653 Screw Machine Drill Bit 6.40mm

Product Description

The VALUE COLLECTION 01293653 is a screw machine length drill bit engineered for general-purpose drilling in metal, wood, and plastic. Built from high-speed steel (HSS) with an oxide finish, it offers added surface hardness and corrosion resistance in everyday shop and field conditions. The bit measures 6.40 mm (0.2520 inches) in diameter with a 118-degree standard point angle and a right-hand cutting direction. Overall length is 70.00 mm (2.76 inches), with a 31.00 mm flute length. The stubby screw machine length profile reduces deflection and improves hole accuracy in drill press and handheld applications. Machinists, pipefitters, electricians, and HVAC technicians commonly reach for this bit when working in tight clearances where a jobber-length bit would be impractical.

This bit is suited for light-to-moderate material removal in residential and commercial service environments. Its straight cylindrical shank seats securely in standard drill chucks. The 2-flute regular spiral design promotes efficient chip evacuation during through-hole and blind-hole drilling. Web-thinned construction at the tip reduces thrust force required to start the hole, making it practical for hand drilling as well as machine operation. Oxide coating helps reduce built-up edge and extends service intervals compared to uncoated HSS bits.

Key Features

• 6.40 mm (0.2520 inch) diameter with 118-degree standard point angle for general-purpose drilling
• High-speed steel construction for durability across metal, wood, and plastic substrates
• Oxide finish improves surface hardness and reduces friction during cutting
• Screw machine (stub) length — 70.00 mm OAL — minimizes deflection in tight spaces
• 2-flute regular spiral design promotes clean chip evacuation
• Web-thinned tip reduces entry thrust force for easier hole starting
• Right-hand cut with straight cylindrical shank for compatibility with standard drill chucks

Compatibility

Designed as a general-purpose screw machine length drill bit fitting standard 3-jaw drill chucks and drill press spindles that accept straight cylindrical shanks within the 5.00 mm to 6.50 mm diameter range.

Installation Notes

This bit is installed by qualified machinists, pipefitters, electricians, and mechanical service technicians. Secure the straight shank fully in the drill chuck before operation and verify chuck tightness to prevent slippage. Always wear appropriate eye protection when drilling. Do not apply excessive side load — screw machine bits are intended for axial drilling only.
