Right-Angle Carbide Mill Cutter 4X28X55mm
This tungsten-steel carbide mill cutter is built for CNC machinery and delivers precise cutting on acrylic, PVC, density board and wood board. The up-down compound single-flute spiral design suits compression wood end-milling tasks. It is supplied as a single piece for industrial use only.
Cutting Diameter 4 mm Flute Length 28 mm Overall
The 4 mm cutting diameter and 28 mm flute length define the maximum depth and width of cut in a single pass. The 55 mm overall length sets the tool holder engagement and reach inside the spindle. These fixed dimensions limit the material thickness and profile geometry you can machine.
Shank Fit and Age Restriction Check
Verify that your CNC collet or tool holder accepts the shank diameter implied by the 4X28X55 mm specification before ordering. The tool is rated for users aged 18 and over and is intended solely for industrial cutting applications, not for hazardous materials or general DIY use.

Questions about this item
Should I choose the 4 mm or 28 mm version of this right-angle drill bit?
The listing specifies a single 4 mm cutting diameter with a 28 mm cutting length; no alternative diameters are offered.
What does the 55 mm overall length mean when the bit is mounted in my CNC router?
The 55 mm total length gives you the full shank-to-tip reach, so allow at least that much Z-axis clearance plus your material thickness.
How does the up-down spiral flute affect chip removal in wood and acrylic?
The compound up-down flute pushes chips both upward and downward, reducing tear-out on top and bottom faces of density board, PVC and wood.
