The Inland trim saw is a small bench-top diamond-blade saw produced by Inland Craft Products of Madison Heights, Michigan, primarily for stained-glass and lapidary use. The saw uses a continuous-rim diamond-impregnated blade, typically 4 to 5 inches in diameter, mounted on a small motor with a water-bath cooling and lubrication system. The saw is one of the standard entry-level pieces of lapidary equipment in North American hobbyist and small-shop use, with a market position similar to the Lortone and Highland Park trim saws at comparable scale.

Function and use

A trim saw is used for cutting small slabs of rough lapidary material, sectioning specimens, and performing the initial cut-and-shape operations preceding cabbing or facetting. Trim saws are distinguished from larger slab saws by their smaller blade size and lower-power motors; slab saws use blades of 8 to 24 inches and are designed for cutting larger blocks of rough into slabs, while trim saws handle smaller pieces and finer detail cuts.

The Inland trim saw operates with the blade partially submerged in a water bath that provides cooling for the blade and the workpiece, suppresses dust, and lubricates the cutting surface. The saw includes adjustable cutting platforms and fence systems that allow controlled feeding of material into the blade. Common uses include trimming rough cabochon material to size before cabbing, sectioning small geode and crystal specimens, cutting tile and small stained-glass pieces, and various small-scale lapidary applications.

Specifications and operation

Typical Inland trim saw specifications include a 1/4 to 1/3 horsepower motor, blade diameter of 4 to 5 inches, working depth-of-cut around 1 to 1.5 inches, water reservoir capacity of approximately 1 to 2 quarts, and overall footprint suitable for bench-top use. The blade is replaceable with various diamond-rim blades from Inland or compatible third-party suppliers, with thinner blades preferred for fine detail work and thicker blades for general cutting.

Operating practice for the Inland trim saw and similar small trim saws includes maintaining adequate water in the bath at all times (running the blade dry damages both the blade and the workpiece and produces hazardous dust), keeping the blade clean and properly tensioned, feeding material slowly and evenly without forcing, and using appropriate eye protection. The blade should be inspected regularly for wear and replaced when cutting performance deteriorates.

Position in the lapidary equipment market

The Inland trim saw is positioned in the entry-level to mid-range lapidary equipment market, with current pricing typically in the $300 to $500 range. The saw is widely available through North American lapidary supply houses (Kingsley North, Rio Grande, Diamond Pacific, Contenti, and others) and through general hardware retailers handling stained-glass equipment. For more demanding lapidary work or larger-scale production, alternatives include the Highland Park, Lortone and various Asian-manufactured trim saws at comparable or slightly higher price points, and full slab saws (Lortone, Highland Park, Diamond Pacific) for larger-format cutting.
