Guhring 9006660033000 Extra Length Drill Bit Hss Tin

Product Description

The GUHRING 9006660033000 is an extra length, high speed steel (HSS) twist drill bit with a titanium nitride (TiN) coating, designed for precision drilling in production and toolroom environments. Measuring 3.30 mm (0.1299 inches) in diameter with an overall length of 84.00 mm (3.31 inches) and a flute length of 55.00 mm (2.17 inches), this bit delivers extended reach where standard-length drills cannot access. The 118-degree drill point angle and web-thinned, tapered web configuration promote clean entry and reduced thrust. A right-hand spiral flute with regular helix evacuates chips efficiently during through-hole and blind-hole operations.

This drill bit is intended for use in bushing applications and is suited for drilling aluminum and similar non-ferrous and ferrous workpiece materials, as indicated by its K, N, and P material code classification. The straight-cylindrical shank with an h8 diameter tolerance seats securely in standard drill chucks and collet holders. The 10xD flute-to-diameter ratio and a maximum drilling depth of 50.05 mm (1.97 inches) make it appropriate for extended-reach holes in precision machining, fixture building, and component manufacturing. It conforms to DIN 339 standards and is classified as a general-purpose grade drill bit.

Key Features

• TiN coating increases surface hardness and reduces friction for longer tool life
• Web-thinned, tapered web lowers cutting thrust and improves chip flow at entry
• 118-degree drill point angle suits a broad range of general-purpose materials
• Straight-cylindrical shank with h8 tolerance for consistent chuck and collet fit
• 10xD flute length ratio provides extended reach versus standard-length bits
• Conforms to DIN 339 for consistent geometry and dimensional accuracy

Compatibility

Designed as an OEM-style replacement or production drill bit for use in standard drill chucks and collet systems accepting a 3.30 mm straight-cylindrical shank. Listed for bushing tool applications per supplier specifications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with rotary cutting tools. Secure the shank fully in the chuck or collet and verify runout before drilling. Always reduce spindle speed and feed rate when drilling deep holes near maximum depth to prevent bit deflection or breakage. Disconnect and lock out all power to the machine before changing tooling.
