A wide range of sizes to meet the broad needs of the work environment.

Demonstrate an outstanding cutting feel with uniquely designed cutting edge shape and angle employing ultra-hard tips with emphasis on durability.

SKS(alloy tool steel) material is selected for the under 5.0mm sizes from the cutting edge giving excellent abrasion and shock resistance. This reduces snapping and bending of drill bits to a minimum.

Use the drill appropriate for the drill bit used.

Be sure to turn off the main switch of the electrical drill and disconnect the power supply plug from the socket before attaching and detaching the drill bit.

Attach the drill bit by pushing in until it stops at the end of the chucking part of the drill, and clamp the drill bit tightly so it will not loosen or come off.

Wear eye protection glasses.

Drill holes vertically against the drilled material surface.

Read the instruction manual for the electrical drill used carefully before use and always observe those instructions to ensure safe and correct operation.
