SEC-Wide Tool Holders
Exp anded SGW Type
■ Characteristics
● Enables efficient roughing of components with long shank.
● Produces coin-shaped chips that will not tangle with the
machinery or the work piece.
■ SUMIDIA Multifunctional Tools With Chipbreakers ■ Application Examples
SUMIDIA Break Master LD Type
● Achieves excellent chip control during traverse cutting/
grooving of aluminum alloy.
● Greatly improves work efficiency through eliminating
LD Type + DA1000
problems caused by chips.

Note: Use caution in regards to the spindle power when using this. If this tool is used with a small lathe, the machine may stop during machining due to insufficient spindle power.
Please use caution especially when machining carbon steel and stainless steel.
Recommended tightening torque (N・m) Caution: Re-griding the cutting edges of the SUMIDIA BreakMaster LD type may affect the chip control performance. ● mark: Standard stocked item (expanded product)
