1. Core Design and Manufacturing Features

One-Flute/O-Flute Geometry :
- Chip removal core : This is the most distinctive feature of the ER1 end mill. The single-edge design provides a large spiral chip removal groove, which can instantly expel the heat and chips generated during cutting at high speeds (typically 24,000 to 60,000 RPM) .
- Anti-melting edge and anti-breakage : This can greatly prevent acrylic, plastic and other materials from "melting" and sticking to the knife due to poor chip removal, or chipping and breakage caused by secondary cutting of chips.
Solid carbide/tungsten carbide :

The blade is usually made of high-particle tungsten steel, which has extremely high rigidity and hardness. It can effectively suppress tool vibration (chatter marks) when subjected to high loads and deep cutting depths, ensuring that the workpiece cross-section is as smooth as a mirror.

2. Main Applicable Processing Materials

The ER1 is a balanced general-purpose end mill, specifically designed for cutting hard, sandwich, and MDF materials that ordinary inserts (such as vibrating cutters and drag cutters) cannot penetrate or that are easily torn apart.

Plastics and polymers : Acrylic, PVC foam board, PC, PET, nylon and engineering plastics.
Metal composite materials : thin aluminum sheet, Dibond (aluminum-plastic composite board), copper sheet.
Wood and Packaging Boards : Medium-density fiberboard (MDF), solid wood boards, plywood, high-density paperboard.
Modern composite materials : carbon fiber sheets, epoxy resin glass fiber sheets.

3. Brief distinction between ER1 and other models (such as ER2, ER62.1)

In the Router Bit Library settings of the IECHO cutting machine, different codes often correspond to different
shank diameters or specific material roughing/fineing logic:

ER1 / ER2 : These are mostly standard 3.175mm (1/8"), 4mm or 6mm shank diameter single-flute all-purpose end mills. Among them, ER1 is most frequently used in daily sign making and cutting medium and thin sheet metal.
ER62.1 / ER64 series : typically designed for specific heavy-duty machining, with different cutting edge lengths (CEL) and overall shape designs (such as ball end mills, corrugated edges for specific metals, etc.).
