Value Collection 01292101 Screw Machine Drill Bit 3.30mm Hss

Product Description

The VALUE COLLECTION 01292101 is a screw machine length drill bit designed for general-purpose drilling in metal, plastic, and wood applications. Built from high-speed steel (HSS) with an oxide finish, it measures 3.30 mm (0.1299 inches) in diameter and carries a standard 118-degree point angle. The shorter-than-jobber overall length of 49.00 mm (1.929 inches) makes it well suited for drill presses, CNC machines, and screw machines where reduced overhang improves rigidity and hole accuracy. Two regular spiral flutes evacuate chips efficiently during through-hole and blind-hole operations. The straight cylindrical shank fits standard drill chucks without modification.

This bit is intended for use in machine shop environments, maintenance and repair operations, and light manufacturing settings where a compact, rigid drill bit is needed. The screw machine length profile reduces deflection in short-hole applications, making it a practical choice for production drilling on drill presses and automated equipment. Right-hand cutting direction is standard for conventional spindle rotation. The general-purpose grade makes it appropriate across a range of common ferrous and non-ferrous workpiece materials.

Key Features

• High-speed steel construction for durability across general-purpose drilling tasks
• Oxide coating provides mild corrosion resistance and reduces friction during cutting
• 118-degree standard point angle for reliable starts on flat and curved surfaces
• Screw machine length (49.00 mm OAL) reduces deflection and improves rigidity compared to jobber-length bits
• Two regular spiral flutes with web-thinned geometry for efficient chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose screw machine length drill bit suitable for use in standard drill chucks accepting a straight cylindrical shank within the 0.00 to 3.50 mm size range.

Installation Notes

Secure the shank fully in the drill chuck before operation and verify chuck runout is within acceptable tolerance to maintain hole diameter accuracy. Power down and lock out the machine before changing bits. Operators should follow applicable shop safety standards and wear appropriate eye protection during drilling operations.
