Giken / Zero burr drills

The original Zero Burr drills

Outstanding straightness with no burrs

Significant cost reduction through process reduction

Drills have a structure closer to an end mill than a drill

R-shape reduces and disperses load at the contact point and smoothly releases in the direction of rotation

Eliminates center drilling, while suppresses burrs

Achieves H6 hole accuracy while omitting reaming

Amazing facts!

── Introducing ideas and technologies ──

In normal drilling, the deburring process on the hole exit side is a problem, but the Zero Burr drill is a special drill that eliminates the need for a deburring process because it does not produce burrs on the hole exit side.

Until now, drills had poor hole position accuracy due to poor bite and straightness, requiring two processes: centering and drilling. The Zero Burr Drill has a 3D shape at the tip for biting, a special wave drill section to reduce the cutting process and heat generation during drilling, and a spiral reamer section to clean up the surface roughness of the hole sides. The fine-curved flute section improves chip evacuation, surface roughness, roundness and positioning accuracy, making previously impossible precision drilling possible only with the Zero Burr Drill.

This is the point!

Combine multiple processes into one

Conventional drilling process

Zero Burr one-shot drilling

This is the point!

Outstanding straightness and beautiful surface finish

This is the point!

Characteristics in figures

Low thrust resistance
Small difference between thrust and torque
At the time of exit, the main load is the torque (cutting off the edge of the hole).

Please use wet drilling

Ensure that work is firmly fixed and drill completely pass through the penetration depth

If work deflection is too large, welding or hole diameter may become large, or a spiral mark may remain inside the bore hole.

PRECAUTION

Please use wet drilling

Ensure that work is firmly fixed and drill completely pass through the penetration depth

If work deflection is too large, welding or hole diameter may become large, or a spiral mark may remain inside the bore hole.
