Capacity is what puts this one on top. The 750X takes anything from 3/32 inch to 3/4 inch, and it lets you set the point angle anywhere between 115 and 140 degrees rather than offering a preset or two. Nothing else here reaches 3/4 inch, so if your index runs to 5/8- or 3/4-inch shanks, this is the only machine on the page that will hold them.
The split-point port is the feature we appreciate most, though. A split point keeps a bit from skating when it starts a hole, and the 750X both restores existing splits and cuts new ones, with a push-to-stop guard that keeps you from grinding a split past the point where the bit still works. Carbide, cobalt, black oxide, TiN-coated, and masonry bits all run on the same installed diamond wheel.
Setup is where it asks for patience. Getting a small bit seated so the wheel meets both lips evenly is the whole skill, and the manual assumes more than it explains — work through a handful of bits you have already written off before you touch the ones you care about. Once the alignment clicks, each bit takes seconds and the edge comes out consistent.
Three years of warranty and a 180-grit diamond wheel that arrives already installed suggest a machine meant to live on a bench. If your bits all sit in a folding index that stops at 1/2 inch, the 500X gets there with a shorter learning curve; the 750X earns its keep once your drilling runs to bigger shanks and mixed materials.
What We Like
- Widest capacity here, up to 3/4 inch
- Point angle adjusts 115 to 140 degrees
- Creates and restores split points
- Handles carbide, cobalt, coated, and masonry
Worth Noting
- Nothing smaller than 3/32 inch fits
This is the one we recommend for a mixed bit drawer: 3/4-inch capacity, a point angle you can set anywhere from 115 to 140 degrees, and split points on demand.
