Guhring 9006600011800 Micro Drill Bit Size 56 Cobalt

Product Description

The GUHRING 9006600011800 is a micro drill bit sized at wire gauge 56 (0.0465 inches diameter), designed for precision drilling in tight tolerances. Built from cobalt high-speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and improved heat resistance in demanding machining environments. The 118-degree faceted point with web thinning promotes accurate entry and reduces thrust force. The tapered web configuration and spiral flute design aid chip evacuation in short-hole applications. Overall length is 0.984 inches, making it suited for use in micro-machining setups, CNC operations, and precision manual drilling where small-diameter accuracy is critical.

This bit is primarily intended for drilling aluminum, non-ferrous metals, and titanium alloys, covering material codes K, M, N, P, and S. It fits production and toolroom environments where wire-gauge micro drill accuracy is required. Maximum drilling depth is 0.230 inches (5.83 mm), and the straight-cylindrical shank at 1.50 mm diameter fits standard collets and drill chucks accepting that shank size. It conforms to DIN 1899 specification and is sold individually with a minimum order quantity of 10 units per purchase.

Key Features

• Wire gauge size 56, 0.0465 inches diameter with tight tolerance of +0.000 to -0.004 mm
• Cobalt construction with TiN coating for heat resistance and extended tool life
• 118-degree faceted point with web thinning for accurate entry and reduced thrust
• Spiral flute, tapered web, right-hand cut for effective chip evacuation
• Conforms to DIN 1899 specification for micro drills
• 5xD flute-to-diameter ratio suited for short, precise through-holes

Compatibility

Designed for use in standard collets and drill chucks accepting a 1.50 mm straight-cylindrical shank. Primary workpiece materials are aluminum, non-ferrous metals, and titanium alloys per material codes K, M, N, P, and S.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or toolroom technician. Secure the straight-cylindrical shank fully in a properly sized collet or drill chuck before operation. Confirm spindle runout is within acceptable limits before use, as runout causes premature breakage in micro-diameter drills. Do not exceed the rated maximum drilling depth of 0.230 inches without retracting to clear chips.
