The size dimensions have an error of approximately 2mm depending on the package.

■3-Ply Cutters

Cutting the shavings to one-third with respect to the cutting width using 3-ply cutters (outer, inner and intermediate cutting blades) has dramatically decreased cracks on the tip corner. This also includes inside cutting edges so debris can be discharged smoothly.

■Compatible with Pipe-Drilling

Pipes and curved-surface materials can be drilled at a throat depth of 25 mm.

Compatible with Pipe-Drilling

■Hole Saw Drilling Efficiency

Hole saw drilling has a smaller cutting area compared to steel drills, enabling short-time drilling.

Hole Saw Drilling Efficiency

■Drilling swarf discharge groove
Drilling swarf is efficiently discharged through the discharge grooves that are also compatible with thick steel plates. Clogging of drilling swarf between the work material and cutting edge makes drilling impossible, which leads to tips cracking and chipping.
■Shavings Escape Hole
An escape hole, which is convenient for shavings removal, is equipped with hole saws of all diameters.
After removing the main unit from the motor, insert the metal rod that fits through the hole, etc., into the shavings escape hole and push out debris.
■Newly developed step center drill
Two-step structure of the center drill tip dampens impacts that occur when the center drill passes through, preventing cracking of the tungsten carbide/ultra-hard tip.
■10 mm/13 mm chuck combination shank Allows for most drill chuck diameters.

■Appropriate Rotation Speed

■Use the drill at a rotation speed appropriate for the drilling work material and diameter.
■When drilling a thick plate with a thickness of 5 mm or more or for continuous cutting, select a lower rotation speed.

Appropriate Rotation Speed

■Peripheral Speed

Stainless Steel	Common Steel	Aluminum
25-35 m/min	40-60 m/min	60-100 m/min

Securely chuck the three-surface section of the shank to prevent swinging or falling.
Do not reduce the rotation speed excessively during drilling. Jamming or tip cracking may result.
Do not hit the cutting edges of the tungsten carbide/ultra-hard tip against any hard object or allow strong contact with the work material that may occur when the center drill passes through. The tip will crack.
In the case of continuous drilling using a drilling machine, watch out for overheating of the cutting edge and use cutting fluid or stop drilling to cool the cutting edge.

Watch out for impacts that may occur when the center drill passes through!
