Walter-titex 5153732 Screw Machine Drill Bit 0.348in

Product Description

The WALTER-TITEX 5153732 is a screw machine length drill bit ground from cobalt vanadium high speed steel for demanding metal-cutting applications. At 0.348 inches in diameter (Letter Size S), it features a 130-degree split point that reduces walking on entry and lowers thrust requirements. The parabolic flute geometry promotes efficient chip evacuation, making it well-suited for deep-hole drilling at a 3xD flute-to-diameter ratio. A web-thinned, tapered web configuration further improves cutting performance in hard and abrasive workpiece materials. The straight-cylindrical shank fits standard drill chucks without modification. This bit is rated as a high-performance, universal-grade tool intended for professional machining and fabrication environments.

This drill bit is designed for use in screw machine, CNC, or benchtop drill press setups where short, rigid tooling is required. Primary workpiece materials include steel, stainless steel, cast iron, hard materials, and non-ferrous metals. With an overall length of 3-5/16 inches and a flute length of 1-9/16 inches, it fits tight-clearance work envelopes common in production machining. The bright, uncoated finish makes it easy to inspect for wear. It is manufactured to DIN, ISO, and BS specification standards, confirming dimensional and tolerance consistency across production runs. Machinists, tool and die technicians, and metalworking fabricators are the primary users.

Key Features

• Cobalt vanadium high speed steel construction for extended tool life in hard and abrasive materials
• 130-degree split point reduces entry thrust and prevents bit walking on smooth or hard surfaces
• Parabolic flute design with 3xD ratio supports efficient chip evacuation in deeper holes
• Web-thinned, tapered web configuration lowers cutting resistance across a range of metal types
• Straight-cylindrical shank compatible with standard keyed and keyless drill chucks
• Manufactured to DIN, ISO, and BS standards with a diameter tolerance of -0.00087 to 0.00000 inches

Compatibility

Compatible with workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals as listed in the Series A1148 specification. Fits standard straight-shank drill chucks used in screw machine, CNC, and bench drill press applications. The 0.348 inch diameter corresponds to Letter Size S per standard drill sizing.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking technicians familiar with drill press, lathe, or CNC machine operation. Ensure the workpiece and machine are secured and all rotating guards are in place before operation. Use appropriate cutting fluid or coolant for the workpiece material, noting that this bit does not have internal coolant-through capability. Inspect the cutting edges and split point for wear before each use and replace if chipping or dulling is observed.
