Hey machinists and tool enthusiasts! This Micro 100 dovetail cutter is seriously professional-grade stuff. We're talking about a 30° included angle dovetail cutter with 2 flutes that's made from solid carbide and coated with AlTiN (that's Aluminum Titanium Nitride for those who want the technical details). The specs are precise: 0.250 cutter diameter, 1/4 shank diameter, 0.161 cutter length, 1/8 neck length, 0.170 neck diameter, and 2-1/2 overall length. What makes this cutter special is how it's engineered for superior rupture strength and amazing machining versatility - perfect for milling full dovetail grooves with drop hole allowance. The corner radii aren't just for looks; they actually enhance tool strength and rigidity. The AlTiN coating is a game-changer too - it handles oxidation temperatures up to 800°C (1450°F) and maintains hardness even when things get hot. This means longer tool life and the ability to run faster feeds and speeds, which is awesome for productivity. It works great with alloy steels, stainless steels, tool steels, nickel alloys, and titanium. Plus, it's made right here in the USA by Micro 100, who've been killing it in the solid carbide tool game for over 45 years. If you're tired of tools that wear out too quickly or don't deliver the precision you need, this dovetail cutter is worth every penny for serious machining work.
