Walter-titex 7377834 4.2mm Solid Carbide Taper Length Drill Bit

Product Description

The WALTER-TITEX 7377834 is a solid carbide taper length drill bit from the DC160 series, designed for high-performance drilling in demanding industrial and machining applications. It features a 4.2 mm (0.1654 inch) diameter, a 140-degree split point, and a TiSiAlCrN coating for extended tool life in hard and abrasive materials. The spiral flute geometry and right-hand cut produce clean, accurate holes, while the through-coolant capability supports higher feed rates and improved chip evacuation in deep-hole operations. This bit is sized to an 8xD flute-to-diameter ratio, with a maximum drilling depth of 37.00 mm. It is installed by machinists and CNC tooling specialists in production and maintenance environments.

The 7377834 is suited for blind hole, cross hole, inclined hole, stack drilling, and through hole drilling operations. The parallel shank with a 6.00 mm shank diameter mounts directly in standard collet chucks and drill bushings without modification. Its DIN 6537 K compliance makes it a direct fit for metric tooling setups in general manufacturing, aerospace component work, and precision fabrication shops that require consistent hole tolerances in harder workpiece materials.

Key Features

• Solid carbide construction with TiSiAlCrN coating for heat and wear resistance
• 140-degree point angle reduces thrust force and improves centering on hard materials
• Through-coolant design supports high feed rates and efficient chip removal
• 8xD flute-to-diameter ratio allows drilling up to 37.00 mm depth in a single pass
• Right-hand spiral flute with parallel shank fits standard collet and bushing systems
• DIN 6537 K compliant for use in metric tooling setups

Compatibility

Designed as an OEM-style replacement or direct addition for DC160-series solid carbide drill bit applications requiring a 4.2 mm diameter, 6.00 mm parallel shank, and DIN 6537 K compliance in standard CNC or manual drill press setups.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before changing tooling. Secure the parallel shank fully within the collet or drill bushing to the manufacturer-specified engagement depth, and verify runout with a dial indicator before production drilling. When using through-coolant, confirm coolant pressure and flow rate are appropriate for the machine spindle before operation.
