Compact CNC Router Bit for Multi-Material Cutting

This single-flute carbide mill cutter measures 4x17x45mm and features an up-down compound spiral design. It is built from tungsten steel for durability in CNC machinery. The tool suits operators cutting acrylic, PVC, density board, and wood board who need a precise, easy cutting experience. It is supplied as a single piece for immediate replacement.

Replaces Worn Single-Flute Bits in CNC Routers

The cutter serves as a direct replacement for dull or damaged single-flute router bits in compatible CNC machines. The jump is worth it when the existing bit no longer produces clean edges on layered or composite boards. The up-down geometry reduces tear-out on both faces of the workpiece. It is not suited for buyers needing multi-flute tools for higher feed rates.

Sustained Cutting in Abrasive Sheet Materials

Under continuous load the tungsten steel construction resists wear when machining abrasive boards such as density board and wood composites. The single flute clears chips efficiently to prevent overheating during long passes. The rainbow coating helps reduce friction and material adhesion. The tool is rated for industrial cutting only and is not for use by persons under 18 years.

Questions about this item

What shank diameter does the 4x17x45 mm carbide mill cutter require in the collet?

The cutter has a 4 mm shank, so the collet or chuck must accept a 4 mm diameter.

How should the up-down spiral flute be oriented when installing the bit in a CNC router?

Install with the cutting edges facing the workpiece; the up-down geometry pulls chips both ways, so the bit must spin in the marked direction and be seated fully in the collet.

When should the single-flute carbide cutter be replaced during heavy board cutting?

Replace when the flute shows visible dulling, chipping, or when cut quality on acrylic, PVC, density board or wood board degrades noticeably.
