Bolt your Traderight 123 block to your mill, drill press, grinder or CNC machine. Jack up your steel bar on your milling machine rather than using parallels. Provide more support with this versatile blocks set.

Check your table and band saw alignment with your 1-2-3 blocks. Use the accurate 90 degree angles to make sure everything is perfectly aligned. Use the precise width to calibrate fence cursors. The Traderight block set ensures accuracy every time.

Check if something is square with your 123 block. You can even check if your square is square. Perfect for checking inside angles to see if they are 90°. Create a precise chisel guide with a cylinder magnet. Ideal for any 1-2-3 blocks set user from beginner to expert.

Your precision 123 block is a piece of hardened 45# stainless steel. There are no moving parts. Treat it well and it will be just as good as the day you bought it twenty years ago — that's the Traderight quality guarantee.

Offset the table or mill from your vice so you can machine all the way through your part. Use your Traderight 1-2-3 blocks to check if parts are square before welding or attaching. Trusted by machinists worldwide for consistent results.
