The Hi-Tech Diamond 4"/5" trim saw is an American-made lapidary saw for trimming cabochon preforms in rock, mineral and glass, and for cleaning up smaller faceting rough. It runs a 1/4 hp direct-drive permanent magnet motor with sealed ball bearings and variable speed from 800 to 3,400 rpm, and it ships with both a 4" and a 5" notched diamond blade, so you get two blade heights for different material. The 5/8" arbor accepts any 4" or 5" blade with the same arbor, and the cross-linked polyethylene housing is rustproof and easy to clean. Against fixed-speed trim saws it offers speed control and a built-in 8 oz coolant reservoir under a removable table; the trade-off is a small table and modest depth of cut. Owners rate it highly, and the 23 ratings average 5 out of 5.

Owners rate the saw 5 out of 5 across 23 ratings, and the praise centers on clean trimming of cabochon preforms and small faceting rough. The two included blade sizes and the variable speed come up as the reasons it handles different material heights.
This trim saw is made in the USA. It is used to trim cabochon preforms from rocks, minerals and glass, and to cleanly trim smaller faceting material. It comes with two silver notched diamond saw blades, one 4" and one 5", so you can choose the blade height that suits your material.
The housing is unbreakable cross-linked polyethylene, which is rustproof and easy to clean. The 1/4 hp direct drive permanent magnet motor has sealed ball bearings and variable speed from 800 to 3,400 rpm. The saw has a 5/8" arbor and accepts any 4" or 5" blade with a 5/8" arbor.
The coolant reservoir is built into the base and holds up to 8 ounces of water. A removable saw table covers the reservoir, which makes cleanup easier. The included splash guard keeps water off the user and on the piece. The blades are designed for cutting and trimming rock material such as turquoise, aqua, garnet, corundum, emerald and ruby.
