Walter-titex 5153727 Screw Machine Drill Bit 0.302 in

Product Description

The WALTER-TITEX 5153727 is a screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built from cobalt and vanadium high speed steel, this bit delivers the hardness and heat resistance required when cutting through stainless steel, cast iron, hard materials, and non-ferrous metals. It carries a 130-degree split point for accurate self-centering and reduced walking on entry. The parabolic flute geometry improves chip evacuation, which keeps the cut clean and reduces heat buildup at depth. At 3.125 inches overall length with a 1.4375-inch flute length, this is a compact, rigid tool suited for close-tolerance drilling on screw machine setups and CNC applications.

This bit is intended for use in production machining environments where tool life and dimensional consistency are priorities. Its 0.302-inch diameter corresponds to Letter N drill sizing, making it a standard selection for tapping prep and close-tolerance bores in steel and stainless components. The straight cylindrical shank fits standard drill chucks and collet holders without modification. A maximum drilling depth of 0.900 inches is typical for screw machine length work. Machinists, tool-and-die technicians, and metalworking shops specify this bit for multi-material applications where a single tool must handle varied stock grades.

Key Features

• Cobalt and vanadium high speed steel construction for heat resistance in hard and abrasive materials
• 130-degree split point reduces entry force and eliminates the need for a center punch on most metals
• Parabolic flute profile with web thinning promotes efficient chip evacuation and reduces thrust
• Bright uncoated finish compatible with most cutting fluids and coolant systems
• Right-hand cut with tapered web configuration per DIN and ISO standards
• Screw machine length body provides added rigidity compared to jobber length equivalents

Compatibility

Designed for use in screw machine setups, CNC machining centers, and drill presses where a straight cylindrical shank tool is required. Rated for primary workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals per Series A1148 universal performance classification.

Installation Notes

This bit is installed and serviced by machinists and metalworking technicians. Secure the shank fully in a drill chuck or collet holder and verify runout before production use. Apply appropriate cutting fluid for the workpiece material, particularly when drilling stainless steel or hardened stock. Do not exceed the rated maximum drilling depth of 0.900 inches without retracting to clear chips.
