Bosch Digital Protractor and Inclinometer with Mitre Calculation
A professional angle measuring tool with 60 cm aluminium arms that reads angles from 0° to 270° to ±0.1°, then works as an inclinometer for slopes from 0° to 360° (±0.05° at 0° and 90°). A built-in point laser carries the slope up to 30 m across a wall, ceiling or roof.
Bosch part number: 0 601 076 400 (also written 0601076400 or 0.601.076.400)
EAN: 3165140781527
As a mitre angle finder, it works out the cutting angle for simple mitres and, from the spring and corner angles, the mitre and bevel settings for compound cuts such as coving and crown moulding, so no separate calculator or conversion table is needed. Separate displays show the angle and the incline, a hold function keeps a reading, and the arms lock to transfer an angle straight to the workpiece. A leg extension, two spirit levels and readings in degrees, percent or mm/m suit joinery, skirting, stairs and handrails, roof work and fit-out.
