3.175×1.2×6 Single Flute Aluminium Spiral Bit Guide
A single flute aluminium spiral bit provides a large chip channel for fine CNC milling in aluminum and compatible non-ferrous materials. This 3.175×1.2×6 mm carbide cutter combines a common shank with a very small 1.2 mm cutting diameter. Its open flute helps remove chips and limit welding when lubrication, feed and spindle speed are correctly balanced.
Fine Aluminum Milling Applications
The 1.2 mm diameter can follow narrow slots, small-radius corners, lettering and detailed prototype geometry. A 6 mm flute supports shallow and precise toolpaths in aluminum signs, panels and small components. Because the cutter is fine, machine runout, workholding and entry strategy must be carefully controlled to avoid overload or breakage.
- Fine aluminum slots and contours
- Small lettering, signs and panel details
- Prototype fixtures and miniature components
- Compatible non-ferrous metal applications
Setup for a 1.2 mm Flat-Tip Cutter
Clean the 3.175 mm collet, check spindle runout and clamp enough of the shank for stable rotation without covering the flute. Keep projection short and secure the workpiece. Use a gentle ramp or suitable entry rather than an aggressive plunge. Begin with a light step-down and conservative cutting load, then adjust after inspecting chips and finish.
Use the machine-approved lubricant, mist or air system to move aluminum chips away from the edge. A productive cut should create distinct chips rather than smeared metal. If the bit chatters or loads, stop the job, clear the flute and review feed, spindle speed, depth and workholding. Avoid dwelling because heat can quickly promote chip welding.
Selecting a Single Flute Aluminium Spiral Bit
Before ordering a single flute aluminium spiral bit, verify shank diameter, cutting diameter, flute length, overall length, flat-tip geometry and cutting direction. Check that slot width, corner radius and depth match the 1.2 mm diameter and 6 mm flute. Alloy grade, tolerance and machine rigidity also influence selection.
JEEFOO Carbide Tools from Guangzhou, China
JEEFOO supplies carbide CNC milling cutters from Guangzhou, China for distributors, manufacturers and workshop users. Sharing the alloy, machine type, collet size and required depth helps the team recommend a suitable tool. Explore more product information on the JEEFOO cutting tools website.
For general background on computer-controlled machining, see the reference on numerical control. Record successful feeds, speeds, lubrication, step-down and tool numbers with the job file so repeat production begins from verified parameters.
For repeat jobs, inspect the collet and cutting edge before every setup. Store the verified alloy, feed, speed, depth and lubrication method with the CNC program. Consistent records help operators reproduce the cut, recognize wear early and avoid unnecessary trial passes.
Frequently Asked Questions
Can a 1.2 mm cutter machine aluminum?
Yes, when the machine has low runout and the alloy, lubrication, feed, speed and cutting depth suit the fine tool. A test cut is recommended.
What do 3.175×1.2×6 dimensions mean?
They commonly identify a 3.175 mm shank, 1.2 mm cutting diameter and 6 mm flute length. Confirm the complete drawing because conventions can vary.
How can breakage be reduced?
Minimize runout and projection, avoid aggressive plunges, keep chips clear and use light passes. Correctly applied single flute aluminium spiral bit geometry can deliver fine details and predictable life.
Production and Ordering Checks
Make a short test cut in the actual alloy before full production. Inspect chip shape, surface finish, cutting sound and spindle load. Verify the 6 mm flute is sufficient for the planned depth. These checks reduce scrap and make replacement orders more reliable.
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.
