Product Identity

This Cleveland Golf end mill is a high-speed steel cutting tool with a 1-inch milling diameter and four flutes. It features a square end style, single-end configuration, and a 30-degree helix angle for general-purpose finishing applications. The bright uncoated finish and 3/4-inch shank diameter suit standard tool holders.

Build Integration

The 1-7/8-inch length of cut and 4-1/8-inch overall length define the tool's reach within a milling setup. Its right-hand cutting direction and centre-cutting design allow for both plunging and peripheral milling operations. The zero corner radius produces sharp internal corners on finished workpieces.

Target User

This tool suits machinists performing general-purpose finishing cuts in ferrous and non-ferrous materials using manual or CNC milling machines. It is not suited for roughing operations requiring chip-breaking geometries or for high-volume production where coated carbide tooling would offer longer tool life.

Questions about this item

At what helix angle does chip evacuation start to limit feed rate on this 1 in. end mill?

The 30-degree helix angle governs chip flow; pushing feed beyond what that angle can clear will cause packing and limit sustained cutting speed.

How hot does the bright uncoated HSS shank get during a full-day finishing run?

The uncoated high-speed steel body and 3/4 in. shank conduct heat directly into the holder, so expect noticeable warmth after continuous cutting — plan for cool-down intervals.

Which tool holder bore matches the 3/4 in. shank on this single-end mill?

You need a holder with a 3/4 in. internal bore — standard Weldon flat, ER collet or shrink-fit — to clamp the straight shank securely.
