5-piece carbide mill cutter set
This set contains five one-flute up-down cut spiral carbide mill cutters sized 4x28. They are made from tungsten steel and supplied as right-angle drills for use with CNC machinery. The compression design helps produce clean edges on both faces of the workpiece. Buyers who need a larger quantity or different flute counts should look elsewhere.
Replaces worn CNC compression bits
The cutters serve as direct replacements for dull or damaged compression end mills in a CNC setup. Switching to a fresh set restores edge quality and reduces tear-out when the previous tooling no longer cuts cleanly. The jump is worth it when finish quality drops or feed rates must be slowed to compensate for wear. This set does not address needs for heavy hogging or non-wood materials.
Handles wood, plywood, density board.
Tungsten steel construction provides the hardness needed for consistent cutting across these sheet goods and solid stock. The one-flute geometry clears chips efficiently in softer woods but may limit feed speed in denser panels. The 4x28 sizing suits standard CNC collets for these applications. Users requiring deeper cuts or larger diameters will need different tooling.

Questions about this item
What shank size do these 4x28 cutters need to fit my CNC collet?
The cutters are 4 mm in diameter, so they require a 4 mm collet or an ER collet that closes to 4 mm.
How do I install these up-down spiral bits without snapping the flute?
Insert the shank fully into the collet, tighten evenly, and run the spindle at the recommended feed rate for wood to avoid excessive side load on the single flute.
When should I replace these tungsten-steel cutters?
Replace them when the up-down edges show visible dulling, chipping, or when cut quality on plywood and particleboard deteriorates despite correct feeds.
