Seco 00037175 Minimaster Milling Shank 3/4 Inch Keyway MM16

Product Description

The SECO 00037175 is a replaceable-tip milling shank in the Minimaster series, designed for use with MM16-style milling tips in CNC milling operations. The shank features a 3/4-inch (0.750 inch) straight keyway shank with a Weldon flat, providing positive rotational drive and secure tool holding under cutting loads. The neck diameter measures 0.630 inches, and the overall length is 2.760 inches. A head length of 0.787 inches and an effective cutting length of 0.394 inches define the working geometry. This toolholder is installed by machinists and CNC operators in production and job-shop milling environments.

This shank is suited for use in vertical and horizontal milling machines, machining centers, and CNC mills that accept 3/4-inch straight-shank toolholders with Weldon flat drive. The MM16 Toolholder Style designation indicates compatibility with the Minimaster MM16 tip platform, allowing quick tip changes without removing the shank from the spindle. Typical applications include profiling, slotting, and general-purpose end-milling in metalworking operations where repeatable tip indexing is required.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool change mode is engaged before installing or removing the shank. Secure the shank in a compatible Weldon-style side-lock holder and tighten the set screw against the flat to the toolholder manufacturer specified torque. Inspect the replaceable tip seat and clamping threads for chips or debris before seating the milling tip.
