Feature

Replaceable head drills

Replaceable type drill with exchangeable heads using an unique radial serration design, for high precision and strength

An exchangeable drill head provides a new cutting edge, higher productivity and cost efficiency with easy tool management.
Regrinding allowance of 1.5mm to 3mm makes further tool cost reductions possible.

MSL type

Stable machining of mild steel, stainless steel, etc.

Overwhelming cutting edge sharpness in mild steel and SUS machining

Newly designed linear cutting edge and special R web thinning enables improved chip evacuation and stable machining

Stable long tool life

New grade improves fracture and adhesion resistance

MTL type

Suitable for high-efficiency drilling of general steel

Excellent cutting edge strength

Large edge treatment is used to reduce breakage of the cutting edge.

Stable machined hole accuracy

X Type thinning achieves excellent centring on entry and stable drilling.

MFS type

Ideal for drilling and burr control on non-flat surfaces

Can be used for high-efficiency spot facing, drilling on non-horizontal surfaces such as inclined and cylindrical surfaces, and interrupted drilling. Also reduces burrs at the hole exit.

Improves machining stability

Achieves high rigidity by employing RS THINNING, which ensures thick web.

MB type

Ideal for drilling rolled steels for welded structures for bridge (single layer and stacked)

1) Gradual Arc Shape J-Flute

Unique wide and smooth flute shape significantly improves chipcontrol and evacuation.

2) Reduces peripheral edge chipping caused by flapping workpieces

Robust Substrate and Reinforced Edge Treatment

3) Robust Substrate and Reinforced Edge Treatment

4) Robust Substrate and Reinforced Edge Treatment
