Value Collection 01350289 Screw Machine Drill Bit 7/16 in

Product Description

The VALUE COLLECTION 01350289 is a screw machine length drill bit designed for high-production drilling in metal, wood, and plastic. Built from high-speed steel (HSS) with an oxide coating for reduced friction and improved wear resistance, this bit delivers consistent performance in jobsite and shop environments. The 118-degree standard point angle suits general-purpose drilling across a wide range of materials. At 3-7/16 inches overall length, the shortened flute-to-shank ratio characteristic of screw machine bits provides added rigidity and better control in drill press and CNC setups. Machinists, maintenance technicians, and fabricators are the typical end users.

This bit is suited for general-purpose drilling in production and maintenance applications where a rigid, short-length bit is preferred over a jobber-length drill. The 7/16-inch diameter (0.4375 inches decimal) and straight cylindrical shank make it compatible with standard drill chucks across benchtop drill presses, CNC machines, and hand drills. The right-hand cutting direction and regular spiral flute geometry support efficient chip evacuation in most common materials. No coolant-through capability is required for the applications this bit is rated for.

Key Features

• 7/16-inch diameter (0.4375 inches decimal) for precise bore sizing
• High-speed steel construction for durability across general-purpose materials
• Oxide coating reduces friction and extends tool life
• 118-degree standard point angle suits a broad range of drilling applications
• Screw machine length (3-7/16 inches OAL) provides extra rigidity over jobber-length bits
• Web-thinned tip reduces thrust and improves penetration efficiency

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard straight-shank drill chucks on drill presses, CNC drilling machines, and hand drills used in metal fabrication and maintenance applications.

Installation Notes

Installation and use should be performed by machinists or qualified tradespeople familiar with rotary cutting tools. Secure the straight cylindrical shank fully in the drill chuck before operation and verify chuck tightness to prevent bit walking or slippage. Always wear appropriate eye protection and ensure the workpiece is clamped or fixtured before drilling. Inspect the cutting edges for wear or damage before each use and replace bits that show chipping or heat discoloration.
