SpeTool Router Bits 1/4 Inch Shank Spiral Router Bit UpCut CNC Router Bits with TAC Coating 1 Inch Cutting Length 2-1/2 Inch Total Length HRC55 Solid Carbide End Mill for Woodworking Wood Cutter

Would recommend this make , good and precise .They even have cutting speed and cutting depths in there website great for setting up CNC program .

Please dont waste your money on this product.I purchased x2 of these, to cut MFC.On any pass it left the top surface all chipped to hell.Even the bottom was bad.I was expecting these to be the dogs, but in fact my older blunt bits from a reputable company work better.Don't say you have not been warned.

Used it on Mango wood for 10 minutes when inside bearing seized and locked after going black.

For background, I run a full sheet CNC, cutting primarily 3/4" maple plywood, MDF and HDF. I had been using high priced A***a end mills for my work and they are great, but very expensive and I found that MDF was hard on the coating which often led to shortened lifespans.When I started looking for more cost effective alternatives I tested a series of bits from SpeTool and I was immediately surprised at the cut quality and durability. Even thin 1/16" bits went the distance if I was mindful of going low and slow on my DOC and speeds.I've moved completely to SpeTools for my straight cut bits, and this was my first purchase of their coated bits.It's a big improvement in durability and friction reduction. These are my new go to bits!What I liked:1. SpeTool end mills are a great value, particularly the 5 packs.2. Coating markedly reduces friction and chatter.3. Longer shank adds cutting depth when needed and puts more of the shank in contact with my water cooled spindle which further cools the bit.4. Available in all sizes with a 1/4" shank. I don't have to change collets.5. All sizes are available in multiple cut types. I typically use uncut and compression cut bits in 1/4" and 1/8".What I wish:Please offer these bits in 5 packs!

I recently switched to the SpeTool Compression Spiral Router Bit for my CNC, and the results on hard woods are phenomenal. The cuts are incredibly clean, with zero splintering, and the bit's durability is impressive. Even after numerous projects, it retains its sharpness, and the reduced vibrations offer unmatched precision. It's a solid upgrade from my usual Amana bits, and I couldn't be happier with the performance. This tool is now a non-negotiable part of my setup. Two thumbs up!

Works great for cutting through wood like butter.
