Groove Gauge, DEPTH micrometerS & MICROMETER HEADS1175 series - dial indicator groovegauges440 & 445 SERIES - DEPTH MICROMETERSA lightweight gauge is used for in-processor bench inspection of oil grooves, snapring retainer grooves, “O” ring seat retainergrooves and similar internal recesses. It isalso useful for checking bore dimensionsand testing for taper, bell-mouth and out-ofroundness.The movable, sensitive gauging contacthas a 12.7mm (2.1/2”) retractable rangeand transfers the measurement through alinear, friction-free transfer mechanism tothe dial indicator. The lower reference jawis fixed and supports the entire weight ofthe gauge and the operator’s hands, thuspreventing incorrect gauging pressure andfalse readings.The reference jaw can be mounted in twopositions on the range adjusting bar. The baritself is also adjustable for greater or lesserrange. A fine adjustment screw and a lockare also provided.• Supplied with two sets of jaws, both readilyinterchangeable.• Three sets of contacts are furnished (Styles1-10, 2-10, 2-20) that can be attached tothe ends of the jaws without replacing theentire jaw. Contacts have flush ends so thatgrooves at the bottom of blind holes can begauged. The contacts are hardened steelwith a hard chrome finish for long life.Starrett 440 Gauge Micrometers are furnishedwith a 64mm (2.1/2”) base and 3.2mm (1/8”)diameter measuring rods.The 445 Series Gauge Micrometers arefurnished with 100mm (4”) bases and have4mm (5/32”) diameter measuring rods.Other base sizes are available.Cat No Range Graduation Base No Of Rods Rod Diameter Description Item No440MZ-75RL0 - 75mm440MZ-150RL 0 - 150mm 0.01mm 63.5mm 6 3.2mmCV152440Z-3RL 0 - 3”3WithRatchetCV127440Z-6RL440Z-9RL0 - 6”0 - 9”0.001” 2.1/2” 691/8” Stop& Lock NutIn CaseCV132CV1423CV147440MZ-225RL 0 - 225mm 9 CV157445MBZ-75RL0 - 75mm• Reading surfaces have a satin chromefinish that resists rust.• Ring-type lock nut for quick and surelocking.• Combination ratchet and speeder foruniform pressure and quicker adjustment.445MBZ-150RL 0 - 150mm 0.01mm 100mm 6 4mmCV4573CV452445MBZ-225RL 0 - 225mm 9 CV462Cat No Range Graduation Item No1175MZ 9.5 - 150mm 0.01mm DQ7671175z 0.375 - 6” 0.0005” dq762749 SERIES - ELECTRONIC digital DEPTHMICROMETER with output.100”(2.54)3.00” (76.2)GROOVE I.D.STYLE 1-10 STYLE 2-10, 2-201.25” (32) PROF.UPPER JAW2.50” (64)MAX.
