CNC milling cutters for fine engraving and light machining, designed to deliver clean, repeatable cuts. The Haosie Carbide End Mills bring confidence to hobbyists and small workshops who need burr-free finishes. Are they suited to regular aluminium, PCB and soft-metal work?
⚡ At a Glance
- • Cutting Quality: Polished carbide edges produce neat, burn-free cuts with minimal burrs
- • Best for: Precision engraving and small-scale CNC machining of aluminium, PCBs and plastics
- • Not ideal for: High-volume industrial machining of large or hardened workpieces
Tungsten carbide construction with a 1mm cutting diameter and a 9mm cutting edge length. A 38mm overall length and 3.175mm (1/8") shank suit common small CNC setups.
Clean, burr-free finishes – thanks to polished carbide cutting edges
Tungsten carbide material is polished and coated, with a 1mm cutting edge diameter and a 9mm cutting-edge length to maintain a sharp shearing profile. Polished edges reduce friction and help prevent burning at typical engraving feed rates.
Neat surfaces and minimal deburring time after milling, particularly useful when working on circuit boards, plastics and aluminium. Reduced finishing work speeds up small-batch production or hobby projects.
Longer tool life – with tungsten carbide construction and protective coating
Carbide composition combined with a protective coating improves wear resistance and thermal stability during cutting. The manufacturing process emphasises polished faces and durable cutting edges to limit premature dulling.
Extended run times between tool changes and fewer replacements for users who mill intermittently or on a low-volume basis. Reliable edge retention helps maintain consistent part quality.
Versatile material compatibility – with 1mm diameter and 3.175mm shank
A 1mm cutting diameter and 38mm overall length with a 3.175mm (1/8") shank match common collet systems and allow access to tight features. Usage notes list circuit boards, plastics, stainless steel and copper among suitable materials.
Allows fine-detail engraving on PCBs and small aluminium parts while fitting standard small-collet routers and CNC spindles. Useful for hobbyists, model-makers and small workshops needing detail work across different materials.

❓ Frequently Asked Questions
Q: What materials can these end mills work with?
A: The product descriptions list aluminium engraving, circuit boards, plastic, stainless steel and copper as suitable materials; user feedback also notes clean cuts on softer woods. Appropriate feed and cutting speeds should be chosen for each material.
Q: What size collet is required for the shank?
A: The shank diameter is 3.175mm, which corresponds to a 1/8-inch collet, making the cutters compatible with common small-collet spindles and routers.
Q: How durable are the cutters?
A: Tungsten carbide construction with a polished, coated finish is specified for wear resistance, and user reviews report long-lasting durability with no overheating during typical use.
