3.175×2.0x12 One Flute Spiral Cutter CNC Guide

The 3.175×2.0x12 one flute spiral cutter is a solid carbide CNC router bit for acrylic, engineering plastics, wood, MDF and light aluminum applications. Its single-flute up-cut geometry creates a large chip channel, supporting efficient chip evacuation and heat removal in narrow slots and profiles.

Applications and Size Selection

Fine slots and profiles in acrylic and plastic sheet
Small-feature routing in wood, MDF and plywood
Light aluminum machining with rigid setup and suitable lubrication
CNC engraving and mortise cutting where chip clearance is important

The specification identifies a 3.175 mm shank, 2.0 mm cutting diameter and 12 mm cutting length. Confirm overall length and machine clearance before ordering or programming.

CNC Setup and Chip Control

Use a clean precision collet, minimize tool extension and support the workpiece securely. Start with parameters recommended by the machine, material and carbide-tool suppliers. Evaluate chip shape, edge finish, spindle load, sound and temperature. Chips should leave the cut and carry heat away. Dust, melted plastic or aluminum built-up edge means feed, speed, depth, air blast or lubrication needs correction. These principles apply to CNC numerical control routers and mills.

JEEFOO Quality and Guangzhou Supply

JEEFOO supplies carbide CNC cutters from Guangzhou, China. Each 3.175×2.0x12 one flute spiral cutter should be checked for shank size, cutting diameter, flute length, edge condition and model identification before packaging. Visit the JEEFOO CNC tools homepage for related single-flute bits and company contact details.

Inspection and Safe Operation

Inspect the carbide edge for chips or cracks, verify the collet is clean and confirm adequate shank engagement. Use machine guarding, eye protection and suitable chip or dust extraction. Stop machining if vibration, unusual noise, excessive heat or poor chip evacuation appears.

3.175×2.0x12 One Flute Spiral Cutter FAQ

Why use a single flute?

A single flute provides more chip space at a small diameter, which can improve evacuation and reduce heat buildup in plastics and aluminum.

How should the first cut be evaluated?

Check chip formation, edge finish, spindle load, vibration and temperature. Adjust one variable at a time and document the stable setup before production.

Function: spiral router bit is perfect for cutting mortises. The up-cut design helps keep the mortise clear of chips and shavings while you cut. Available in high speed steel and solid carbide.
