- Efficient, precise measurement for setup blocks: simplify wood work by easily adjusting cutter height or stop position with clearly readable scales. The unit is adjustable from 1/64 in to 1-1/16 in, with an accuracy of 1/64 in. - Simple operation: quick-adjust knob to change measurements, movable reference faces, and a dial lock for repeatable settings. - Height and depth dual-scale: easily dial in precise distances between the drill bit and the table surface. Ideal for fine-tuning router bit heights and table saw cut depths, with dual scales for improved control. - Broad applicability: delivers precise readings for table saw depth, drill depth, and fence distance. A must for achieving correct test cuts and other woodworking tasks. - Practical applications: - Fine-tune router bit height for accurate finishing passes. - Calibrate table saw cut depth and fence distance for repeatable rips. - Set and verify drilling depth for multiple-hole projects.
