Walter-titex 5537158 Screw Machine Drill Bit 7/32 in Carbide

Product Description

The WALTER-TITEX 5537158 is a screw machine length solid carbide drill bit designed for high-performance drilling in demanding production environments. Built to DIN and ISO standards, this bit measures 0.2188 inches (7/32 inch) in diameter with a 140-degree X-treme Plus point angle and a double coating finish. The straight-cylindrical shank and web-thinned, tapered web configuration promote clean entry and reduced thrust. With coolant-through capability and a 2-flute regular spiral design, it is suited for shops running high-volume or CNC drilling operations where tool life and hole quality matter.

This drill bit is engineered for universal tool performance across a wide range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. The screw machine length format makes it a practical choice for short-reach drilling applications on machining centers, drill presses, and CNC lathes. The A3289DPL series targets production machinists and toolroom professionals who need consistent, repeatable results across multiple materials in a single tool.

Key Features

• Solid carbide construction with double coating for extended tool life in hard and abrasive materials
• 140-degree X-treme Plus point angle for fast, accurate starts and reduced walking
• Web-thinned tapered web lowers thrust requirements and improves chip evacuation
• Coolant-through design supports high-speed machining with internal coolant delivery
• Straight-cylindrical shank for compatibility with standard drill chucks and collet holders
• Meets DIN and ISO standards; series A3289DPL

Compatibility

Designed as a screw machine length replacement drill bit for use in CNC machining centers, drill presses, and lathes where a 0.2188-inch (7/32-inch) diameter straight-shank carbide bit is required. Suitable for drilling steel, stainless steel, cast iron, hard materials, and non-ferrous metals per the A3289DPL series specification.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the straight-cylindrical shank fully in a compatible drill chuck or collet holder before operation, and verify runout is within acceptable tolerance for the application. Engage coolant-through supply when available to maximize tool life and chip clearance. Always inspect the cutting edges for wear or chipping before each use and replace the bit if any damage is detected.
