Walter-titex 5293782 Solid Carbide Screw Machine Drill Bit 7/16

Product Description

The WALTER-TITEX 5293782 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial applications. Built to Series A6181TFT specifications, it features a 150-degree Form V+A drill point and a web-thinned, tapered web configuration that reduces entry force and improves chip evacuation. At 0.4375 inches (7/16 inch) in diameter with a 2-ply right-hand spiral flute, this bit delivers consistent, accurate holes in tough materials. Coolant-through capability makes it well-suited for sustained production drilling where heat management is critical. Licensed machinists, tool-and-die professionals, and CNC operators are the primary users.

This drill bit is rated for universal tool performance across a broad range of primary workpiece materials including cast iron, hard materials, non-ferrous metals, stainless steel, and steel. Its screw machine (stub) length format gives it added rigidity compared to jobber-length bits, making it ideal for close-tolerance drilling on machining centers, CNC lathes, and drill presses where reduced overhang and vibration control matter. The straight-cylindrical shank conforms to DIN 6535HA specification and fits standard toolholders and chucks sized for 12 mm shank diameters.

Key Features

• Solid carbide construction (grade K30F) for wear resistance in hard and abrasive materials
• 150-degree Form V+A drill point with web thinning for low thrust and self-centering entry
• Coolant-through design supports internal coolant delivery for heat control in deep or high-speed drilling
• Regular spiral flute geometry promotes efficient chip evacuation across workpiece material types
• Straight-cylindrical shank to DIN 6535HA for reliable gripping in standard toolholders
• Meets DIN and ISO standards; rated for universal tool performance across multiple material families

Compatibility

Designed as a direct-fit replacement for Series A6181TFT screw machine length drill bits with a 0.4375 inch diameter and a 12 mm straight-cylindrical shank conforming to DIN 6535HA. Applicable to toolholders and chucks accommodating bits in the 0.4000 to 0.4500 inch diameter range.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator familiar with carbide tooling procedures. Always power down and lock out the machine before inserting or removing the bit from the toolholder or chuck. Carbide is brittle — avoid lateral impact or side-loading during handling and setup. Verify that coolant-through supply lines are properly connected before running the spindle when using internal coolant delivery.
