Walter-titex 7377135 Carbide Screw Machine Drill Bit

Product Description

The WALTER-TITEX 7377135 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding shop and production environments. Built on the DC160 series platform with a Universal Advance performance rating, this bit features a 140-degree drill point angle, a 2-flute spiral configuration, and a straight-cylindrical shank. The solid carbide construction with a coated finish delivers rigidity and wear resistance needed when drilling cast iron and steel. Right-hand cut geometry and a 3xD flute-to-diameter ratio support efficient chip evacuation at typical production feed rates. Licensed machinists and tool-and-die professionals are the primary installers of this bit.

This drill bit is suited for screw machine operations and short-hole drilling applications in production machining environments. It covers a drill bit diameter range of 0.2500 to 0.3000 decimal inch (6.50 to 8.00 mm) and supports a maximum drilling depth of 24.00 mm. Primary workpiece materials are cast iron and steel, making it a practical choice for job shops, CNC machining cells, and manual drill press setups where consistent hole quality in ferrous materials is required. The bit conforms to DIN and ISO standards.

Key Features

• Solid carbide construction with coated finish for wear resistance in ferrous materials
• 140-degree drill point angle reduces thrust and improves centering on hard materials
• 2-flute spiral design with 3xD flute ratio promotes chip evacuation in blind and through holes
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters
• DC160 series Universal Advance classification for general-purpose production use
• Conforms to DIN and ISO standards; drill bit diameter tolerance m7

Compatibility

Designed as a screw machine length solid carbide drill bit compatible with standard straight-shank drill chucks and collet systems used in CNC and manual machining applications for cast iron and steel workpieces.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Confirm chuck or collet bore matches the shank diameter before tightening. Follow machine manufacturer feed and speed recommendations for solid carbide tooling in the specific workpiece material to avoid premature edge failure.
