Walter-titex 5057087 Screw Machine Drill Bit 0.089 in

Product Description

The WALTER-TITEX 5057087 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 hardness and heat resistance needed when working through tough materials. It measures 0.089 inches in diameter (Wire Size 43) with an overall length of 1-9/16 inches and a maximum drilling depth of 0.400 inches. The 130-degree split point and parabolic flute geometry promote aggressive chip evacuation and accurate self-centering without a pilot hole, reducing setup time in production environments.

This screw machine length drill bit is suited for use in CNC machining centers, drill presses, and hand-held power tools where a shorter, stiffer bit profile reduces deflection. It is specifically rated for drilling cast iron, stainless steel, hardened steel, non-ferrous metals, and other hard materials. The straight-cylindrical shank seats securely in standard drill chucks. Fabricators, machinists, pipefitters, and general contractors working with metal components will find this bit appropriate for close-tolerance, high-cycle drilling tasks. It conforms to DIN, ISO, and BS standards and is classified as a high-performance, universal-duty bit under Series A1148.

Key Features

• Cobalt and vanadium high speed steel construction for elevated heat and wear resistance during hard-material drilling
• 130-degree split point with web thinning for self-centering entry and reduced thrust force
• Parabolic flute profile at a 3xD flute-to-diameter ratio promotes rapid chip evacuation and prevents packing
• Screw machine (stub) length design increases rigidity and reduces bit deflection in tight or repetitive setups
• Straight-cylindrical shank fits standard drill chucks without modification
• Meets DIN, ISO, and BS standards; Series A1148 designation for verified dimensional consistency

Compatibility

Designed as an OEM-compatible replacement or direct-fit drill bit for use in any standard drill chuck accepting a straight-cylindrical shank at 0.089 inches diameter. Rated for cast iron, hard materials, non-ferrous metals, stainless steel, and steel workpieces.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or tradesperson familiar with proper cutting speeds and feeds for the target material. Ensure the drill chuck is fully tightened and the workpiece is secured before beginning any drilling operation. No coolant-through capability is present on this bit; use an appropriate external cutting fluid when drilling stainless steel or other hard alloys to extend tool life. Inspect the bit for chipping or wear before each use and replace if the cutting edge is compromised.
