Micro 100 AR-12 Brazed Tool Bit

The Micro 100 AR-12 is a single-point brazed tool bit made from HAWA carbide with a zinc shank. It measures 4.5 inches in length and features a 3/4 inch shank width for right-hand turning operations. Weighing 0.65 pounds, this new hand tool is built for precision machining tasks.

Ideal for machinists needing a durable carbide bit

This tool suits professionals performing right-hand turning on compatible equipment where a 3/4 inch shank fits. It is not for users requiring left-hand cutting geometry or a different shank size. Buyers who need indexable inserts or a specific coating not listed here should look elsewhere.

3/4 inch shank width determines holder compatibility

The shank width of 3/4 inch is the critical specification that decides if this bit fits your tool holder. Verify your machine's holder accepts this dimension before ordering. The 4.5 inch overall length and HAWA carbide material support the cutting performance once mounted.

Questions about this item

How long does the 4.5 In length last before the HAWA tip wears down?

The 4.5 In overall length provides a large volume of HAWA carbide; under sustained cutting the tip wears gradually and the long shank allows repeated regrinds before replacement is needed.

Does the 3/4 In wide shank get hot or vibrate during all-day machining?

The 3/4 In wide shank adds mass that absorbs vibration and spreads cutting heat, so the bit runs cooler and quieter than narrower bits during continuous use.

What holder do I need to clamp the 3/4 In shank securely?

A standard 3/4 In tool post or boring bar holder with a matching square pocket is required; the bit is a blank brazed carbide insert with no built-in clamping features.
