Router and milling bits designed to produce neat slots and clean edge milling for hobby and light workshop use. For precise slotting and reliable finishing, the sourcing map End Mill Router Bits combine heat-treated HSS-AL with a four-flute upcut spiral for improved chip evacuation. Are these cutters well suited to aluminium, wood and PVC projects?
⚡ At a Glance
- • Cutting Quality: Sharp four-flute geometry with wide spiral grooves for tidy slots and smoother finishes
- • Best for: Hobbyists and small workshops needing precise slotting, carving and light metal milling
- • Not ideal for: High-volume industrial production or heavy-duty machining of very hard steels
Heat-treated HSS-AL construction combines hardness with wear and heat resistance. Four flutes and an upcut spiral improve chip removal while enabling 20mm cutting depth and a 1/4" shank fit.
Cleaner slots and faster passes - thanks to four-flute upcut spiral
Four cutting flutes create multiple cutting edges while a wide, upcut spiral groove channels chips away from the cut. Heat-treated HSS-AL keeps flutes sharp under regular workshop loads.
Fast chip evacuation reduces clogging and helps deliver tidier slotting and smoother side milling, useful for finishing and engraving tasks.
Versatile material compatibility - with heat-treated HSS-AL construction
HSS-AL is heat-treated for improved hardness, wear resistance and heat resistance compared with untreated steels. The geometry targets non-ferrous metals, mild steel, plastics and timber.
Suitable for aluminium, cast iron, copper, magnesium alloy, plastic, wood, mild steel and other non-ferrous metals, ideal for mixed-material projects.
Stable holding and reach - with 1/4" shank and 60mm overall length
A 1/4" shank fits common collets and router chucks while a 60mm total length and 20mm cutting depth let the cutter reach deeper slots. Recommended feed rate starts low and increases gradually to avoid vibration.
Ability to perform deeper slotting and accessible mounting on standard routers makes setup straightforward for small workshops and hobby CNC rigs.
✨ The 4 Key Reasons for sourcing map End Mill Router Bits
