SPEED TIGER Carbide Tapered Ball End Mill

The SPEED TIGER ITBTA1000392 is a carbide tapered ball end mill designed for CNC carving and milling tasks. It suits machinists and fabricators working with wood, alloy steels, hardened steels up to HRC45, and cast iron. The 1 mm tip radius and 3.92 degree single side angle support detailed contouring and finishing passes. This tool is not for buyers who need a larger tip radius or a different shank diameter.

Micro Grain Carbide with nACo Coating

The cutter uses micro grain carbide for toughness and wear resistance during high-performance cutting. An nACo titanium aluminum silicon nitride coating lubricates the tool for stability at high temperatures and offers better heat resistance than TiAlN, TiN, or TiCN coatings. The 1/4 inch shank fits standard collets and holders for secure mounting. Flutes are ground in an ISO-9001 certified factory to ensure consistent geometry and cutting quality.

Verify Shank and Tool Clearance Before Ordering

Confirm your machine spindle or collet system accepts a 1/4 inch shank diameter. Check that the 3 inch overall length and 1-1/4 inch cutting length provide sufficient reach without holder interference. Ensure the 3.92 degree taper angle matches the draft angle required for your specific workpiece geometry. This single flute count tool is sold individually and is not suited for applications requiring a higher flute count for chip evacuation.

Questions about this item

What does the nACo coating on this 1mm radius tapered ball end mill allow at high cutting speeds?

The nACo (AlTiSiN) coating lubricates the end mill for stability at high temperature and superior wear resistance at high cutting speeds, offering better heat resistance than TiAlN, TiN or TiCN coatings.

What shank diameter must the holder accommodate for this 3 inch overall length carbide end mill?

The holder must accommodate a 1/4 inch (0.25 inch) shank diameter to fit this tool.

How many flutes does this carbide tapered ball end mill have, and what is the first step when installing it?

This end mill has 2 flutes; the first step is to securely clamp the 1/4 inch shank in a compatible collet or chuck before starting the machine.
