Walter-titex 5153733 Screw Machine Drill Bit 0.358in

Product Description

The WALTER-TITEX 5153733 is a screw machine length drill bit designed for high-performance drilling in demanding shop and field applications. Built from cobalt vanadium high speed steel with a bright, uncoated finish, this bit delivers the hardness and heat resistance required when working through stainless steel, cast iron, hard materials, and non-ferrous metals. It features a 0.358-inch diameter, a 130-degree split point, and a parabolic flute geometry that promotes efficient chip evacuation. The straight-cylindrical shank ensures positive seating in standard drill chucks. This bit is sold individually and is intended for use by machinists and skilled tradespeople who require precision and durability in production or maintenance drilling environments.

This drill bit is suited for screw machine operations and general-purpose drilling on a wide range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. Its shorter screw machine length profile improves rigidity and reduces deflection in tight setups. The parabolic flute design and web-thinned split point reduce the thrust force required at entry and help maintain hole accuracy at depth. It is commonly used in manufacturing, mechanical contracting, and industrial maintenance settings where tight diameter tolerances and consistent performance are required across production runs.

Key Features

• Cobalt vanadium high speed steel construction for elevated heat and wear resistance
• 130-degree split point with web thinning for reduced entry thrust and self-centering action
• Parabolic flute geometry promotes fast, clean chip evacuation
• Straight-cylindrical shank fits standard three-jaw and collet-style drill chucks
• Screw machine length body increases rigidity and reduces deflection versus jobber-length bits
• Diameter tolerance of -0.00087 to 0.00000 inches ensures consistent, on-spec hole sizing
• Meets DIN, ISO, and BS specification standards

Compatibility

Designed as a Series A1148 screw machine length drill bit suitable for use in standard drill chucks, CNC machining centers, drill presses, and screw machine spindles accepting a straight-cylindrical shank. Compatible workpiece materials include steel, stainless steel, cast iron, hard materials, and non-ferrous metals per manufacturer specification.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tradespeople familiar with rotating cutting tools and associated machinery. Ensure the spindle and workpiece are fully secured and the machine is at a complete stop before installing or removing the bit. Verify chuck or collet capacity is appropriate for the 0.358-inch straight-cylindrical shank before seating. Follow applicable shop safety standards and machine manufacturer guidelines for speed, feed, and coolant selection based on workpiece material.
