Walter-titex 6618752 Carbide Drill Bit 3.4 Mm

Product Description

The WALTER-TITEX 6618752 is a solid carbide jobber length drill bit engineered for demanding metal cutting applications in professional machining environments. Measuring 3.4 mm in diameter with a 140-degree drill point angle and a TiNAl coating, this bit delivers high heat resistance and extended tool life across a range of workpiece materials. The two-flute design with a 12xD flute-to-diameter ratio supports efficient chip evacuation, and the coolant-through construction allows internal coolant delivery directly to the cutting zone. Machinists and tool-room professionals install this bit in CNC machining centers and precision drilling operations.

This drill bit is suited for use in both production and job-shop environments where tight tolerances and consistent performance are required. It handles a broad range of workpiece materials including cast iron, steel, hard materials, non-ferrous metals, and superalloys and titanium. Compatible tool applications include blind holes, cross holes, inclined hole exits, and stack drilling. The straight-cylindrical shank seats securely in standard drill chucks and collet holders sized for a 6 mm shank diameter.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiNAl coating provides high-temperature resistance and reduces built-up edge
• Coolant-through design delivers cutting fluid directly to the drill tip for heat management
• 140-degree split-point geometry reduces thrust force and improves centering on entry
• 12xD flute ratio supports deep-hole drilling up to 48 mm maximum drilling depth
• Meets ANSI and ISO standards for consistent dimensional accuracy with m7 diameter tolerance

Compatibility

Designed as an OEM-style replacement or direct-fit option within the DC150-12-03 series, compatible with standard straight-cylindrical shank tool holders and chucks accepting a 6 mm shank. Rated for cast iron, hard materials, non-ferrous metals, steel, and superalloys and titanium workpiece materials per material codes H, K, N, P, and S.

Installation Notes

Installation should be performed by qualified machinists or tooling technicians following standard machine shop procedures. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the straight-cylindrical shank fully in the collet or chuck and verify runout before beginning a cut. Enable coolant-through supply before drilling to protect the cutting edge and promote chip clearance.
