Walter-titex 5057210 Screw Machine Drill Bit 5/16 Inch

Product Description

The WALTER-TITEX 5057210 is a screw machine length drill bit designed for high-performance drilling in a wide range of materials. Built from vanadium high speed steel with a bright uncoated finish, this bit features a 130-degree split point and a parabolic flute geometry. The 5/16 inch diameter and compact 3-1/8 inch overall length make it well suited for stub-length applications where rigidity and hole accuracy are priorities. The web-thinned, tapered web construction reduces entry force and improves chip evacuation, making it a reliable choice for production drilling environments where consistency matters.

This drill bit is intended for right-hand cutting and is rated for use in aluminum alloy, aluminum silicon alloy, brass, copper alloy, stainless steel, and steel. The straight-cylindrical shank fits standard drill chucks without adapters. It is appropriate for use in machine shop environments, maintenance and repair operations, and fabrication work where screw machine length drills are specified. The Series A1148 designation places it within a recognized high-performance product line conforming to BS and DIN specification standards.

Key Features

• 5/16 inch diameter with a tight tolerance range of -0.00087 to 0.000 inches for consistent hole sizing
• 130-degree split point reduces walking and lowers thrust requirements at entry
• Parabolic flute profile accelerates chip removal and reduces heat buildup
• Web-thinned tapered web improves cutting efficiency across multiple workpiece materials
• Vanadium high speed steel construction provides elevated hardness and wear resistance
• Screw machine length (3-1/8 inch OAL) delivers added rigidity compared to jobber length bits

Compatibility

Rated for drilling aluminum alloy, aluminum silicon alloy, brass, copper alloy, stainless steel, and steel. Fits standard straight-cylindrical drill chucks. Conforms to BS and DIN specification designations. UNSPSC Code 23241635.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Ensure the workpiece is securely fixtured and the drill chuck is properly tightened before operation. Follow machine manufacturer guidelines for spindle speed and feed rate based on workpiece material. Inspect the cutting edges for wear or damage before each use and replace the bit if the split point or flute geometry is compromised.
