Tungaloy continuously expands the advantages of its AddMeisterDrill exchangeable-head drill solution into a smaller diameter range. Ten new DMC precision drill heads have been added to the line for diameters ranging from 4.0 mm (.157″) to 4.9 mm (.192″), expanding the entire range from 4.0 mm (.157″) up to 5.9 mm (.232″).

ANCA has designed a special dental drill loading kit including tailored RoboMate pallets for FX machines using a Fanuc 200iD robot loader. The pallet top allows a reduction of the insertion depth of the shank with an 8mm pocket depth, so that drills with only 10mm of available shank length can be loaded.

In addition to the cooling and geometry, Walter's new WJ30RZ and WJ30RY grades also boost performance because their highly wear-resistant TiAlSiN-based layer applied using HIPIMS coating technology takes the form of a complete coating for 3 and 5xDc (WJ30RZ grade) and a point coating for 8×Dc (WJ30RY grade).

The drill features a new grade, with an improved multi-layer physical vapor deposition (PVD) coating.

The DMH drill head geometry is designed to protect drill corners and provide effective chip evacuation, making the drill head suited for applications that involve drilling holes through thin plates. The increased cutting edge strength resists thin-plate snapback and wear from exit burrs, preventing drill edges from fracture damage during machining for minimum machine downtime.

Featuring superior cutting performance of solid carbide drills and the ease-of-use of the DrillMeister exchangeable head drill series, AddMeisterDrill small-diameter exchangeable head drills allow quick and secure exchanges of extremely small drill heads thanks to its dedicated key. In addition, unique coolant outlets furnished on the drill body provides an increased ratio of through-coolant supply for improved chip evacuation and process security.

DrillMeister is a super productive, accurate, and cost efficient exchangeable-head drill series. Its DMF counterboring drill head line now includes diameters from 20.0 mm to 25.9 mm, increasing the entire standard range from 6.0 mm to 25.9 mm (from .236″ to 1.020″).

The anti-friction coating reduces radial distortion helping improve run-out. Parlec P3 ER collets have a repeatably accuracy of 0.0001" and are sealed for coolant pressures up to 2,000 PSI due to a special slotting design.

Individually, the CoroDrill 462 offers high performance hole making up to 3.00 mm. Ideal for drilling both blind and through holes, the drill is capable of machining a variety of ISO materials, including ISO P, M, K, N, S, O and H. With a drill depth of 6xD, the CoroDrill 462 offers manufacturers a versatile drilling solution.

AH9130 is Tungaloy's latest PVD technology specifically designed for high-performance drilling applications. With better wear resistance compared with existing first-choice grade AH725, the grade delivers extremely long tool life in drilling applications, particularly of carbon steel and alloy steel.
