YINGHUA 10pcs Carbide Router Bit Set

This set supplies ten solid-carbide straight-slot bits for CNC routers and right-angle drills. Each cutter uses a two-flute geometry in tungsten steel to handle engraving and profiling tasks. The pack is aimed at workshop operators who need a ready supply of identical tools for repeat jobs. New condition ensures every flute is sharp from the first pass.

Replaces Worn Carbide Bits In CNC Workflows

Swapping dull cutters for this ten-piece box restores clean edges on acrylic, PVC, nylon, resin, wood and plywood. The jump is worth it when finish quality drops or feed rates must be lowered to avoid tear-out. Buyers who need specialised profiles such as compression or ball-nose geometries will not find them here.

Sustained Cutting In Abrasive Sheet Materials

Tungsten steel retains hardness during long runs in plywood and resin composites where glue lines accelerate wear. Two flutes evacuate chips steadily, reducing heat build-up that can burn edges on acrylic or PVC. The 17 mm flute length and 45 mm overall length suit shallow pockets and through-cuts without excessive deflection. Industrial use only; not for operators under 18 years.

Questions about this item

What shank diameter does the 4X4X17X45 bit need in a collet?

The bit has a 4 mm shank, so use a 4 mm collet or chuck that grips the full shank length without over-tightening.

How should the 10-piece carbide set be mounted to avoid run-out?

Insert each bit until the flutes clear the collet face, then tighten evenly; the common mistake is leaving a gap that lets the cutter wobble at speed.

When do the tungsten-steel flutes on these 17 mm cut-length bits need replacement?

Replace a bit when the cutting edges show visible rounding or the router requires noticeably more feed force in wood, acrylic or PVC.
