Guhring is extending its range of drills with the arrival of the company’s new Micro Precision Drills. Developed for the precision drilling of challenging materials, Guhring says that its Micro Precision Drills deliver rigidity, stability, performance and precision when drilling small holes.

Manufactured from a sub-micron carbide substrate, the latest drilling line is suitable for use in challenging materials such as stainless steel, heat-resistant steels, titanium and titanium alloys, Inconel, Hastelloy, Monel, copper, brass and bronze alloys. Until now, this range of materials has proven particularly difficult to drill, especially in small diameters from 0.5 to 3mm. What enables the new Guhring Micro Precision Drills to process this wide range of materials is the strong carbide substrate and innovative geometry. The next-generation geometry technology incorporates a ground facet point, concave cutting edge and web thinning – all in one drill.

This combination delivers high performance as the special facet point increases the cutting data, so end users can process holes at higher speeds than ever before. Additionally, the concave cutting edge significantly improves chip evacuation, which is critical for small-hole drilling where swarf clearance can cause performance issues. The new drills also incorporate Guhring’s next-generation coating technology with high heat resistance. This impervious coating technology maximises tool life and performance even when drilling the most difficult of materials, reports the company, retaining edge performance for prolonged periods under demanding conditions.

The h7 diameter tolerance Guhring Micro Precision Drills are available in drilling depths of 3, 6, 10, 15, and 20xD, in 0.05mm increments from 1 to 3mm with additional diameter increments in the range for pre-threading and specialist requirements.
