Coatedx6x4x20x50 Solid Carbide Square End Mill for CNC Metal

Coatedx6x4x20x50 Solid Carbide Square End Mill is a precision cutting tool designed for precision slotting, side milling, profiling and general metal machining up to approximately HRC55. It is manufactured for stable CNC machining and consistent cutting performance.

Solid Carbide Square End Mill Features

Solid carbide construction for rigidity, wear resistance and dependable tool life.
Precision-ground cutting geometry supports accurate dimensions and a consistent machined finish.
Suitable for CNC machining with correctly selected speed, feed, pass depth and cooling conditions.
Designed for professional metalworking, mold making and precision component production.
Standard dimensions and customized cutting-tool specifications are available.

Applications and Usage

The Coatedx6x4x20x50 model is suitable for precision slotting, side milling, profiling and general metal machining up to approximately HRC55. Confirm material hardness, machine rigidity, tool runout and workholding before production. Use conservative test parameters when machining a new alloy or an unfamiliar workpiece.

Use a clean collet or tool holder that matches the shank.
Keep overhang as short as the application allows.
Select cutting parameters for the tool diameter, flute geometry and workpiece material.
Maintain appropriate cooling, lubrication and chip evacuation.
Replace worn, chipped or damaged tools before continued machining.

How a Solid Carbide Square End Mill Works

A solid carbide square end mill in the Coatedx6x4x20x50 configuration combines four flutes, a coated 4 mm cutting diameter, a 6 mm shank, a 20 mm cutting length and a 50 mm overall length. The square-end geometry produces flat floors, straight walls and defined shoulders. Four cutting edges can support stable finishing and productive material removal when the chip load, spindle speed and engagement are correctly matched to the workpiece.

Metal Machining Applications

This cutter can be used for profiling, shoulder milling, pocket finishing, shallow slotting and flat-bottom feature machining in compatible steels, cast iron, stainless steel or non-ferrous metals. Material grade, hardness and heat treatment must be considered before selecting parameters. The same settings should not be applied to every metal because cutting force, chip formation and heat generation differ substantially.

Machine Setup and Cutting Guidance

Clean the collet or holder and spindle taper before installation. Clamp the 6 mm shank securely and keep overhang as short as the required reach allows. Check tool runout, machine rigidity and workholding because four-flute tools rely on balanced edge loading. Verify tool length offset, spindle rotation and fixture clearance before starting the program.

Begin with conservative spindle speed, feed per tooth, axial depth and radial engagement. Observe chip form, cutting sound, spindle load and surface finish, then adjust gradually. Apply the coolant, air or lubrication method appropriate for the material and tool specification. Maintain chip evacuation so hot chips are not recut. A controlled test cut is recommended for a new alloy, machine or toolpath.

Buyer Selection Checklist

Confirm flute count, cutting diameter, shank diameter, flute length, overall length, helix and coating grade before ordering. Buyers should also state the metal grade, hardness, maximum depth, machine type, holder and required finish. For long-reach pockets, thin walls or high-hardness materials, provide a drawing so tool geometry and cutting strategy can be reviewed.
