Cleveland C75029 End Mill Purpose

The Cleveland C75029 is a six-flute high-speed steel square end mill designed for general milling operations. It suits machinists and maintenance teams needing a centre-cutting tool for slotting and profiling tasks. The uncoated finish works well in a range of ferrous and non-ferrous materials. Buyers requiring coated tooling for high-temperature alloys or abrasive composites should select a different cutter.

Build Integration

The cutter features a 3/4 in Weldon flat shank that locks securely into standard end-mill holders. Its 1.375 in length of cut and 3 5/8 in overall length determine the reach available inside a fixture. The 1.25 in milling diameter sets the width of each pass. Shops without Weldon-compatible holders or needing a different shank style cannot use this tool directly.

Sustained Load Behaviour

Six flutes distribute chip load evenly, promoting smoother finishes during extended cuts. High-speed steel construction tolerates moderate heat buildup better than carbide in interrupted cuts. The uncoated surface relies on proper coolant or lubrication to maintain edge life over long runs. Operators pushing aggressive feeds without flood coolant will see accelerated wear.

Questions about this item

How long can the 1.25 in cutting diameter run before the High Speed Steel edge wears down?

The High Speed Steel construction resists heat buildup during milling, but tool life depends on workpiece material, feed rate, and coolant use rather than a fixed time limit.

Does the 1.375 in length of cut generate excess heat or vibration during continuous pneumatic operation?

The uncoated High Speed Steel body and Weldon flat shank dissipate heat evenly, and the six-flute design reduces chatter for smoother, quieter cuts in extended runs.

What shank size must my tool holder accept for the 3/4 in Weldon flat on this end mill?

Your holder must accommodate a 3/4 in diameter shank with a Weldon flat to lock the mill securely in place.
