Micro 100 Brazed Tool Bit AR-8
This Micro 100 AR-8 brazed tool bit is a single-point cutting tool made from HAWA carbide with a zinc shank. It measures 3.5 inches long and 1/2 inch wide with a right-hand configuration. The item weighs 0.25 units and arrives in new condition for immediate workshop use.
Suited for right-hand turning on compatible tool
Machinists needing a right-hand carbide bit for general turning will find this tool matches the required geometry. Shops requiring left-hand cutting action or a different shank width should select another tool bit. Buyers who want more length or a different carbide grade must look elsewhere.
Right-hand cutting orientation
The right-hand design determines the direction of cut and must match the tool holder and machining operation. Verify that your setup requires a right-hand bit before ordering. This single specification decides whether the AR-8 fits the application.

Questions about this item
How do I mount this 3.5 in carbide tool bit in a lathe tool holder, and what alignment mistake causes poor cuts?
Clamp the 1/2 in shank squarely in the holder with the carbide tip on centre height; the common error is letting the tip sit above or below centre, which changes the effective rake and leaves a rough finish.
What wear or maintenance should I expect on the HAWA carbide tip over time?
The brazed carbide edge will gradually dull; plan to regrind the top rake and side relief on a diamond wheel when surface finish degrades, and replace the bit if the braze joint ever shows cracks.
What is the first limitation I will hit when taking continuous heavy cuts with this right-hand bit?
The 1/2 in shank cross-section limits rigidity, so chatter appears before the carbide itself fails; reduce depth of cut or increase support to keep the tip stable.
