Walter-titex 5153730 Screw Machine Drill Bit 0.332 in

Product Description

The WALTER-TITEX 5153730 is a screw machine length drill bit engineered for high-performance drilling in demanding trade and industrial applications. Built from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, this bit features a parabolic flute design and a 130-degree split point for fast chip evacuation and accurate hole entry. The straight-cylindrical shank provides secure chuck retention in standard drill presses, CNC machines, and handheld power tools. Licensed machinists, pipefitters, and mechanical contractors rely on this type of tooling for precision-diameter holes in tough base materials.

This drill bit is suited for use on cast iron, stainless steel, hardened steel, non-ferrous metals, and other hard materials. The screw machine length format - shorter than a jobber-length bit - delivers added rigidity and reduced deflection in close-clearance setups, making it a practical choice for machine shop work, fabrication bays, and field mechanical service. The Series A1148 designation places it within a standardized product family built to DIN and ISO specifications.

Key Features

• 0.332 inch (Letter Q) diameter, tolerance -0.00087 to 0.000 inches for consistent bore size
• Cobalt Vanadium High Speed Steel construction for heat resistance and edge retention in hard materials
• Parabolic flute geometry promotes rapid chip clearing and reduces heat buildup
• 130-degree split point with web thinning for self-centering entry and reduced thrust load
• Screw machine length for enhanced rigidity and minimal deflection in tight setups
• Compliant with DIN, ISO, and BS specification standards

Compatibility

Designed for use in standard straight-shank drill chucks and compatible with a wide range of drilling applications across cast iron, stainless steel, hard material, non-ferrous metal, and general steel workpieces. Bit size falls within the 0.3000 to 0.3500 inch diameter range of the A1148 series.

Installation Notes

This tooling is installed by machinists, millwrights, and mechanical tradespeople using drill presses, lathes, or CNC equipment with compatible straight-shank chucks. Secure the shank fully in the chuck and confirm concentricity before drilling. Use appropriate cutting fluid or coolant for stainless steel and hard material applications to preserve edge life. Always wear eye protection and ensure the workpiece is properly clamped before starting the spindle.
