●Regular type MSUSZ440

Variety in variation.
Length of cut lined up with L/D=2 or 3 (Some sizes).

●Long neck type MSUSZ440-LN

Long neck type for prevention of interference with work material.

●Adopted unequal flute spacing and unequal helix angle

By adopting unequal flute spacing and unequal helix angle to prevent chattering produced by sympathetic vibration.
Enhanced tool life and machining surface quality.

Unequal Flute Spacing

Unequal Helix Angle

●Enhanced peripheral cutting edge

Developed a stronger flute to resist high load machining, even with small-diameter φ1 can also realize high efficient machining.

●Specialized flute shape!

A large chip pocket with improved chip removal ability at the front flute, and a high rigidity design with a strong core at the end part realized high efficiency machining.

●Chip control by the step of the end tooth

By design the step of the longest end tooth, short end tooth, and big chip pocket, divide each cutting area when drilling helped chip removal smoothly.

By adopting special end profile and optimized high heat-resistance MUGEN-COATING PREMIUM to realize stable long time machining on stainless steels.

Please increasing the coolant flow rate and pressure as much as possible, and supply it sufficiently to the machining point and flute.
Please change the depth of cut or feed when chips could not remove smoothly during drilling.
Please be noted there would be a possible tool chipping or breakage when the chip removal is insufficient.
