Walter-titex 5153720 Screw Machine Drill Bit 0.261 in

Product Description

The WALTER-TITEX 5153720 is a screw machine length drill bit engineered for high-performance drilling in demanding industrial and trade applications. Built from cobalt vanadium high speed steel with a bright uncoated finish, this 0.261-inch (Letter G) bit features a 130-degree split point and parabolic flute geometry for efficient chip evacuation and reduced thrust. The two-flute, right-hand cut design with a tapered web configuration delivers consistent performance across a broad range of workpiece materials. Licensed trades and machining professionals install this bit in drill presses, CNC equipment, and handheld power tools where screw machine length and straight-cylindrical shank compatibility are required.

The 5153720 is suited for drilling cast iron, stainless steel, hardened materials, non-ferrous metals, and general steel in both production and maintenance environments. Its 2-3/4-inch overall length and 1-7/32-inch flute length make it compact enough for tight-clearance applications. The 3xD flute-to-diameter ratio supports drilling to a maximum depth of 0.800 inches. This bit is a practical choice for machinists, millwrights, pipefitters, and field technicians who require a universal-performance stub-length drill in Letter G sizing.

Key Features

• Cobalt vanadium high speed steel construction for heat resistance and extended tool life in hard materials
• 130-degree split point reduces walking and lowers required feed pressure at entry
• Parabolic flute geometry accelerates chip removal and reduces heat buildup in deep holes
• Web-thinned, tapered web configuration improves cutting efficiency and centering
• Straight-cylindrical shank fits standard drill chucks without adapters
• Meets DIN, ISO, and BS standards for dimensional and performance compliance

Compatibility

Series A1148 screw machine length drill bit designed for use in standard drill chucks accepting a straight-cylindrical shank. Compatible workpiece materials include cast iron, hard material, non-ferrous metal, stainless steel, and steel.

Installation Notes

This bit is installed by machinists, maintenance technicians, and trade professionals using drill presses, lathes, or CNC drilling equipment. Secure the shank fully in the chuck and verify runout before beginning a cut. Use appropriate cutting fluid for stainless steel and hard materials to manage heat and extend tool life. Inspect the cutting edges for wear or chipping before each use and replace the bit if edge integrity is compromised.
