| Tooke Gage Microgroover |
 |
| The Microgroover is a major accessory tool for creating coating incisions for film thickness measurements with the Tooke Paint Inspection Gages. This tool greatly extends the range of the measuring technique to include almost any coating on any substrate. The Microgroover is especially effective on hard and brittle (concrete) materials, as well as soft or elastomeric (rubber) substances. In addition, fibrous composites are incised easily and cleanly. Aside from film thickness measurements, small-scale operations of cutting, grinding, sawing, and polishing can be performed with this useful cordless power tool. |  |
| Description |
|
| The Microgroover is a high-speed rotary tool for creating the small, almost microscopic, incisions required for measurements with the Tooke Paint Inspection Gage. This technique completely eliminates the deformations of coating and substrate which may occur when conventional gage cutting tips are used. The high-speed cutter, usually with either tungsten carbide or diamond-studded surfaces, “erodes” away surface material in a precise pattern, leaving adjacent and underlying areas totally undisturbed. Hard, brittle, tough, fibrous, tender, or elastomeric materials exhibit clean, nontearing, controlled disintegration under the rotary cutter. |
| Construction |
|
| The Grinder unit is the Dremel Minimite Model 750 Cordless Rotary Tool. It comes in a flexible carrying case that can be attached to the Paint Inspection Gage carrycase. It is furnished complete with charger, and with special accessories for grooving operations. The Microgroover adaptation utilizes for groove cutting operations drill-like grinder tips (cylindrical face cutting). |

| DF-MG402A | Microgroover Complete with charger, carrycase, cutting tools, and special accessories for thickness measurement preparations. |
| DF-MG402A-09 | Conical Carbide Cutter This cutter may be used in place of the MG402-02 Cylindrical Carbide Cutter supplied with the MG402 MICROGROOVER. The advantages of the conical cutter are twofold. First, it makes the minimum possible “footprint” on the work surface. Second, it is capable of setting to “X” values well above 4X. Thus it is clearly preferred for use on thin films (< 1 mil) and on curved surfaces. This cutter has a pointed tip with a conical cutting surface having a solid angle of 30 degrees. The material is tungsten carbide. It is used similarly to the cylindrical tip, but with varied protrusions of the cutter in the chuck. These settings are achieved using a small plastic step template for precise length adjustments to achieve calibration. Cutter - Tungsten Carbide, 1/8" dia. x 1-1/2" length, 30 degree conical tip Template - Notched plastic plate, length positions 1,2,3,4,5,6 Shipping Wt. - 2 oz. |
