Walter-titex 5691061 Taper Length Drill Bit 8.5mm Carbide

Product Description

The WALTER-TITEX 5691061 is a taper length solid carbide drill bit in the A6589DPP series, engineered for precision drilling in demanding industrial and trade applications. Built from K30F-grade solid carbide, it delivers the hardness and wear resistance required for consistent performance in tough materials. The bit features a 140-degree point angle with an X-treme D point type and double point coating, supporting clean entry and extended tool life. With a 12xD flute length-to-diameter ratio and coolant-through capability, it handles deep-hole operations with effective chip evacuation and thermal control. Licensed machinists and tooling professionals are the primary users of this bit.

This drill bit is suited for a range of hole types including blind holes, cross holes, inclined holes, stack drilling, and through hole drilling. The 8.5 mm diameter and 138 mm flute length make it appropriate for medium-depth drilling operations in production machining environments. Its parallel shank with a 10 mm shank diameter seats securely in standard tool holders conforming to DIN 6535 HA. The web-thinned, tapered web configuration reduces thrust force at the cutting tip, making it practical for both manual and CNC-controlled setups.

Key Features

• Solid carbide K30F construction for high hardness and wear resistance
• 140-degree X-treme D point with double point coating for precise entry and long service life
• Coolant-through design supports chip evacuation and heat management in deep holes
• 12xD flute-to-diameter ratio enables maximum drilling depth of 123 mm
• Web-thinned tapered web reduces cutting thrust and improves centering
• Right-hand spiral flute with parallel shank conforms to DIN 6535 HA standard

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC machining centers and drill presses accepting parallel shanks per DIN 6535 HA with a 10 mm shank diameter.

Installation Notes

This bit is installed by machinists or tooling technicians in CNC or manual drilling equipment. Ensure the machine spindle and tool holder are powered down and locked out before changing tooling. Verify the shank seats fully and is secured within a DIN 6535 HA-compliant chuck or collet. Activate coolant-through supply before beginning drilling cycles to maintain proper chip clearance and bit temperature.
