Value Collection 01350271 Screw Machine Drill Bit 27/64

Product Description

The VALUE COLLECTION 01350271 is a screw machine length drill bit designed for general-purpose metal drilling in production and maintenance environments. Built from high-speed steel (HSS) with an oxide coating for added lubricity and surface protection, this bit measures 27/64 inch (0.4219 inch) in diameter with a standard 118-degree point angle. The overall length is 3-3/8 inches, making it shorter than jobber-length bits and better suited for close-quarter drilling in drill presses, screw machines, and CNC turret applications. Licensed machinists and maintenance technicians are the primary installers.

This bit is suited for drilling ferrous metals, mild steel, aluminum, and similar materials in both shop and field settings. The shorter screw machine length improves rigidity and reduces deflection, which is especially useful in repetitive production drilling. The straight cylindrical shank seats securely in standard drill chucks and collets. The 2-inch flute length provides adequate chip clearance for the intended cutting depth range of this format.

Key Features

• 27/64 inch diameter with 0.4219 inch decimal equivalent for precise sizing
• 118-degree standard point angle for general-purpose drilling in metal
• High-speed steel construction handles moderate heat and cutting loads
• Oxide coating reduces friction and provides light corrosion resistance
• Screw machine length (3-3/8 inches OAL) improves rigidity over jobber bits
• Web-thinned construction reduces thrust force at the cutting tip
• Right-hand cut with regular spiral flute for standard drilling operations

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill chucks and collets accepting straight cylindrical shanks in the 0.4000 to 0.4500 inch diameter range.

Installation Notes

Install and remove drill bits only when the machine spindle is fully stopped and power is locked out per standard machine-guarding practice. Secure the straight shank fully in the chuck or collet before operation to prevent slipping. Use appropriate cutting fluid for the workpiece material to extend bit life and improve hole finish. Inspect the cutting edges for wear or chipping before each use and replace the bit if edge integrity is compromised.
