Cleveland C41618 Square End Mill 2 Flute Hss 0.5 in

Product Description

The CLEVELAND C41618 is a two-flute, single-end square end mill ground from high speed steel (HSS) and designed for general-purpose milling operations in machine shop and production environments. With a 0.5-inch mill diameter and a 1-inch length of cut, it handles slotting, profiling, and peripheral milling in a compact regular-length geometry. The 30-degree helix angle promotes smooth chip flow and reduces cutting forces, making it well suited for both ferrous and non-ferrous workpieces. Right-hand cut and right-hand flute configuration follow standard convention. Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. This tool is used by machinists, toolroom operators, and CNC setup technicians in job shops and production facilities.

The C41618 is intended for milling cast iron, non-ferrous metals, and steel. Its uncoated HSS construction makes it a cost-effective choice for lower-speed manual mills and CNC machining centers where coated carbide is not required. The 0.5-inch straight cylindrical shank with Weldon flat accepts standard ER collets and Weldon-style end mill holders. Regular length geometry fits most standard mill setups without clearance concerns. The HG-2 series designation identifies it as part of Cleveland's catalog of general-purpose HSS end mills.

Key Features

• 0.5-inch mill diameter with 1-inch length of cut for standard slotting and profiling depths
• High speed steel construction for use in lower-speed or manual milling applications
• 30-degree spiral flute helix for efficient chip evacuation and smooth cutting action
• Centercutting design permits direct plunge milling without a pilot hole
• Right-hand cut, right-hand flute configuration compatible with standard spindle rotation
• Straight cylindrical shank with Weldon flat for secure tool holding in ER and Weldon holders

Compatibility

Designed for use in manual knee mills, CNC vertical machining centers, and similar equipment accepting a 0.5-inch shank. Suitable for cutting cast iron, non-ferrous metals, and steel as noted in the manufacturer specifications for the HG-2 series.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully into the tool holder and torque the set screw to the holder manufacturer specification, aligning the Weldon flat with the set screw. Confirm spindle direction is right-hand before engaging the cut. Inspect the cutting edges for chips or wear before each use and replace the tool if edge condition is compromised.
