3/4-Inch HSS Double-End Square End Mill

This 3/4-inch high-speed steel end mill serves machinists and maintenance shops that need a general-purpose finishing tool for ferrous and non-ferrous metals. The double-end design provides two cutting ends on a single shank, extending usable life in repetitive milling operations. A 30-degree helix and right-hand cut suit conventional milling machines and CNC setups alike. Bright uncoated finish keeps cost low for short-run jobs.

Double-End Versus Single-End Tooling

Switching from a single-end mill to this double-end version makes sense when the same diameter is used repeatedly and tool-change time matters. The second cutting end effectively doubles the available cutting edges without changing holders or offsets. The upgrade is worth it when finishing passes dominate the cycle and the 1-5/16 inch length of cut reaches the required depth. If roughing or heavy material removal is needed, a dedicated rougher or coated single-end mill remains the better choice.

Installation Notes And Common Issues

The 3/4-inch shank fits standard 3/4-inch end-mill holders or collets; secure it with the full bearing length engaged to prevent pull-out. Runout exceeding a few thousandths will chip the sharp 0.000-inch corner radius and degrade surface finish. Bright HSS dulls faster in abrasive alloys, so monitor flank wear and flip to the second end before catastrophic failure. Flood coolant or a suitable mist is recommended to evacuate chips from the two-flute geometry.

Questions about this item

What size tool holder does the 3/4-inch shank on this end mill require?

The shank diameter is 3/4 inch, so it fits a standard 3/4-inch collet or end-mill holder with a matching bore.

How should I secure the double-ended cutter in the spindle to avoid run-out?

Clamp on the plain shank section only, not on the flutes, and tighten the holder evenly so both 1-5/16-inch cutting ends run true.

When the bright uncoated flutes wear down, can the tool be resharpened?

Yes, the high-speed steel body with 30-degree helix and zero corner radius can be reground multiple times until the overall length becomes too short.
