Cleveland C40514 Drill Mill 3/4 in 2 Flute 90 Point Tin Hss

Product Description

The CLEVELAND C40514 is a high speed steel drill mill designed for combined drilling and milling operations in a single tool. With a 0.75 inch diameter and a 90-degree point angle, it transitions cleanly from center drilling into peripheral milling without a tool change. The titanium nitride (TiN) coating extends surface hardness and reduces friction, improving tool life in ferrous and non-ferrous materials. Two right-hand flutes with a 30-degree helix angle provide efficient chip evacuation during cutting. This tool is handled by machinists and tool-and-die professionals working on manual and CNC mills, VMCs, and knee mills.

The C40514 suits precision machining applications where drilling and end milling must occur in the same operation, reducing setup time and tool changes. Its 1.3125 inch length of cut supports moderate-depth pockets and through-hole operations in workpiece materials typical of job shop and production environments. The 3/4 inch shank diameter ensures a rigid grip in standard ER or side-lock toolholders. It is appropriate for ferrous alloys, aluminum, and plastics where high speed steel performance is acceptable.

Key Features

• Combined drill and end mill geometry eliminates tool changes between drilling and milling steps
• 90-degree point angle centers accurately and produces flat-bottomed entry geometry
• TiN coating increases surface hardness and reduces built-up edge in continuous cuts
• 30-degree right-hand helix supports efficient chip flow and smooth finish
• 3/4 inch shank diameter compatible with standard toolholding systems
• High speed steel construction allows resharpening for extended tool life

Compatibility

Designed as an OEM-style drill mill for use in standard 3/4 inch toolholders on manual and CNC milling machines requiring combined drill-mill operations.

Installation Notes

Installation and use should be performed by qualified machinists familiar with rotating cutting tools and machine tool safety. Power down and lock out the spindle before inserting or removing the tool from the holder. Verify toolholder runout and clamping torque per the toolholder manufacturer specification before operation. Inspect the cutting edges and TiN coating for wear or chipping before each use.
