Drills

MultiDRILL

EMUGE MultiDRILL™ is made of a unique sub-micro grain carbide grade that is harder than conventional carbide grades for drilling, yet it retains the ability to withstand shock and chipping. MultiDRILL features advanced TIALN-T63 coating utilizing nano-layer technology with surface hardness exceeding standard TIALN-based coatings, for reduced friction at high temperatures.

Star Cutter Express

Extreme Feed RT 100 XF drills

Expanding the reach of the RT 100 XF carbide drills to include 12xD lengths, Guhring offers exceptional metal removal rates in a full array of diameters and lengths. The powerful RT 100 XF features include:

PunchDrill

PunchDrill features patent-pending geometry with an innovative chip breaker which produces short chips to control machining forces. The new drill also has newly developed surface treatments and a hard diamond-like coating specially designed for this application to provide reliable chip removal and increased process reliability. When high-speed PunchDrill is used at the recommended feed and speed, axial force is reduced by half.

DB131/DB133 Micro Carbide Drills

DB131/DB133 Supreme Solid Carbide Micro Drills Come With Internal and External Coolant Capability

A new type of flute design reliably evacuates chips, even with the tinniest drills. This capability ensures that hole depths up to 30 × Dc can be easily achieved with the DB133 Supreme micro drill with its 140° point angle. The DB131 Supreme micro pilot drill features a 150° point angle. Emulsion, oil or minimum quantity lubrication (MQL) can all be used as a coolant with these drills. The DB133 drills without internal coolant are available in a diameter range from 0.020-0.116 in. (0.5-2.95 mm).

DC118 Supreme Solid Carbide Drill

The 180°-point angle makes the DC118 Supreme ideal for plunging into inclined or round surfaces because the drill is guided quickly on the margins and centered accurately. At the same time, burr formation remains extremely low. The protective corner chamfer on the cutting edges protects against rapid wear, which significantly increases tool life compared to drills without a protective chamfer. The excellent rigidity of the drill is a third feature which sets it apart from the competition.

Custom-Designed Double Contour Single Flute Gundrill

Double Contour Gundrill with Extended Carbide Head Capability

The machining improvements are achieved by a special cutting drill contour with an added rear contour configuration that acts like a guide pad while the drill remains in the bushing, keeping the tool on location. Once the drill is in the cut, these guide pads continue to force the tool to cut a straight path for the remainder of operation.

Single Flute Extended Length Gundrill

Drills Designed to Machine Straight Deep Holes

In a field study on an aluminum cylinder head, the application of the extended drill was able to achieve a tool life of 2,000 parts per drill when machining holes of 8 mm diameter at 5,000 RPM in the cut and a feed rate of 1200mm/minute. Prior to the deep hole gundrill operation, there were two twist drill passes with the gundrill connecting the center portion of this feature in the head.
