Walter-titex 5153736 Screw Machine Drill Bit 0.386 in

Product Description

The WALTER-TITEX 5153736 is a screw machine length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built from cobalt and vanadium high speed steel with a bright uncoated finish, this bit delivers durability and heat resistance in tough materials. It measures 0.386 inches in diameter with an overall length of 3.5 inches and a flute length of 1.6875 inches. The 130-degree split point reduces walking and enables faster penetration without a center punch. The parabolic flute geometry improves chip evacuation, making it well suited for deep-hole drilling at a 3xD depth ratio. Licensed HVAC technicians, machinists, pipefitters, and plumbing professionals will find this bit appropriate for precision hole-making in ferrous and non-ferrous materials.

This screw machine drill bit is intended for use in cast iron, hardened material, non-ferrous metals, stainless steel, and carbon steel. The shorter screw machine length body provides added rigidity compared to jobber-length bits, making it a reliable choice for drill press work, CNC setups, and handheld power drilling where bit deflection is a concern. The straight cylindrical shank fits standard drill chucks. It complies with DIN, ISO, and BS specifications, confirming dimensional and performance consistency for professional use.

Key Features

• Cobalt and vanadium high speed steel construction for extended tool life in hard and abrasive materials
• 130-degree split point reduces thrust force and eliminates center-punch requirement on most surfaces
• Parabolic flute design accelerates chip removal and reduces heat buildup during extended drilling cycles
• Web-thinned, tapered web configuration lowers cutting resistance at the tip
• Screw machine length body increases rigidity and reduces deflection versus jobber-length alternatives
• Meets DIN, ISO, and BS dimensional standards for consistent fitment and interchangeability

Compatibility

Designed as a Series A1148 screw machine length drill bit compatible with standard straight-shank drill chucks. Suitable for drilling cast iron, hard material, non-ferrous metal, stainless steel, and steel workpieces across general machining and trade applications.

Installation Notes

Installation and use should be performed by qualified machinists, pipefitters, or trade professionals familiar with rotating cutting tools. Secure the workpiece firmly and ensure the drill chuck is properly tightened before operation. Disconnect power to the drill press or tool before changing bits. Do not exceed the manufacturer-rated spindle speed for the workpiece material and bit diameter.
