SPEED TIGER Carbide Down-Cut Router Bit

The SPEED TIGER ISED1-4-2 is a 1/4" carbide end mill designed for general-purpose routing in wood, aluminium, copper, MDF and a range of steels. Its down-cut geometry pushes chips downward for a cleaner top surface. The cutter suits CNC operators and woodworkers who need a single tool for mixed-material jobs.

Materials and users it suits

Micro-grain carbide handles carbon steels around 225 Brinell, alloy steels between 225 and 325 Brinell, pre-hardened steels up to 45 HRC and hardened steels in the 40 to 45 HRC range plus cast iron. Buyers who need up-cut chip evacuation, compression spirals or larger diameters should look at other tool types.

Cutting capacity and headroom

The 1/4" cutting diameter and 1" cutting length give enough reach for typical pocketing and profiling passes. The 1/4" shank fits standard collets while the 2-1/2" overall length keeps the tool rigid. Very deep slots or high-volume production runs may exceed the flute length or wear life of this single flute geometry.

Questions about this item

What collet size does the 1/4" shank on this carbide bit require?

The 1/4" shank fits a standard 1/4" collet on your router or CNC spindle.

Can the down-cut geometry on this bit handle the same aluminium and MDF I already cut with up-cut tools?

Yes, the micro-grain carbide cuts aluminium, copper, MDF, wood and steels up to HRC45, but the down-cut action pushes chips downward instead of lifting them.

How do I verify the bit is performing correctly after setting spindle speed and feed rate?

Look for clean edges without tear-out on the top surface and consistent chip evacuation; contact the seller for cutting-condition data if results differ.
