Quick-change cutter type!
High-speed and high-precision drilling is possible with a minimal force.

• The cutter can be changed with a single action.
• Highly-improved carbide tip is used for the cutting teeth.
• The center pin realizes accurate hole starting without bit walk.
• Circumferential cutting limits cutting areas, thus allowing large-bore cutting with electric drills of small horsepower.

• Steel plates, shape steel plates, stainless steel plates, cast iron plates, etc. of up to 35mm (1-3/8") thickness.
• Ideal for drilling work for shipbuilding, bridge, frame, steel-frame building, etc.
