This tool greatly extends the range of the measuring technique to include almost any coating on any substrate. The Microgroover adaptation utilizes drill-like grinder tips for groove cutting operations (cylindrical face cutting).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. Kit Contents Micro-Metrics MG402 MicrogrooverInstalled bitPositioning block (behind at left)Carry caseBit protectorBattery charger Click image to enlarge Specifications The grinder unit is the Dremel Minimite® Model 750 Cordless Rotary Tool. It comes in a flexible carrycase that can be attached to the paint inspection gage carry case. It is furnished complete with charger, and with special accessories for grooving operations. The grinder is powered by rechargeable Ni-Cad batteries in a removable battery pack (included). A full charge should suffice for 100 or more measurements. The charger will completely recharge in three hours.Grinder UnitDremel 750 MiniMite® Cordless ToolMotor4.8 volt DC; 5/10 thousand RPMCarrycaseFlexible plastic 2" x 2" x 8"Battery PackPlugs into 110 volt AC outletChargerPlugs into bottom of grinder or chargerAccessoriesBits and Positioning BlockShipping Weight2 pounds Operation The Microgroover is a high-speed rotary tool for creating the small, almost microscopic, incisions required for measurements with the Tooke Paint Inspection Gage/Gauge. This technique completely eliminates the deformations of coating and substrate which may occur when conventional gage cutting tips are used.Using the Microgroover in the 4 x positionThe 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, non-tearing, controlled disintegration under the rotary cutter. Click image to enlarge For precise and rapid measurements, a “drum mode” of cutting was developed. In this mode the grinder is fitted with the No. 9902 tungsten carbide cutter (or equivalent) installed in precise position. With the round rim of the Microgroover in continuous contact with the work surface, the unit is pivoted until the tip contacts the surface. A light touch with the rotating tip creates the required incision.Using the Microgroover in the 1x position Click image to enlarge The cutting angles (slopes) of 1×, 2× and 4× are accomplished by using the positioning block to elevate the contact shoulder of the Microgroover as required. The required shoulder elevations are as follows:Cutting AngleShoulder Elevation1x0.97" (block resting on narrow face)2x0.41" (block resting on wide face)4x0.00" (block not used)Using the Microgroover in the 2x position Click image to enlarge Principle When the incision is examined with the Tooke Paint Inspection Gage/Gauge microscope, it will appear as a partial cylindrical cavity, with the cavity wall angling gradually upward to the paint surface. Where the wall of the cut penetrates the substrate surface, the paint film above it describes a crescent shape. The crescent shape is cross-hatched in the drawing below. The thickness is correctly read axially across the thickest part of this shape.Counting the number of graduations of the microscope reticle within this zone (11 of the smallest hash-marks in the cross-hatched area of the example below), the correct observed thickness for the 1×, 2×, or 4× position of the grinder will be the count divided by 1, 2, or 4 respectively; or, in the example shown below, 11 / 1 = 11 mils, 11 / 2 = 5.5 mils, or 11 / 4 = 2.75 mils.Reading the Microgroover incision Click image to enlarge Albuquerque Industrial https://www.abqindustrial.net/store/coating-inspection-c-97/coatings-miscellaneous-c-97_55/micro-metrics-mg402-microgroover-p-561.html Sun, 08 Jun 2025 00:43:55 +0000 USD 561 Micro-Metrics 991 MG402 https://www.abqindustrial.net/store/images/MG402-c1.jpg https://www.abqindustrial.net/store/images/additional/mg402-microgroover-107.jpg https://www.abqindustrial.net/store/images/additional/mg402-microgroover-109.jpg https://www.abqindustrial.net/store/images/additional/mg402-microgroover-110.jpg https://www.abqindustrial.net/store/images/additional/mg402-microgroover-111.jpg https://www.abqindustrial.net/store/images/additional/mg402-microgroover-112.jpg 561 https://www.abqindustrial.net/store/coating-inspection-c-97/coatings-miscellaneous-c-97_55/micro-metrics-h-501-pencil-hardness-gauge-p-562.html https://www.abqindustrial.net/store/index.php?main_page=product_reviews&products_id=562 Pencil Hardness Gauge / GagePerforms the ASTM D3363 Pencil Hardness TestAssess quantitatively the rigidity or firmness of organic coatings applied to rigid substrates such as metal.The H-501 Pencil Hardness Gage/Gauge is practical for use in the laboratory, on the production line, or in the field to assess quantitatively the rigidity or firmness (elastic modulus) of organic coatings applied to rigid substrates such as metal. Hardness values may define requirements for particular coatings applications or may be used to evaluate state-of-cure or aging of coating.The Pencil Hardness Gage/Gauge is unique in that it provides a compact single unit for performing this test, rather than a set of easily lost individual pencils. The importance of this advantage is especially apparent when several individuals are working with a single instrument. Kit Contents Micro-Metrics H-501 Pencil Hardness Gaugefourteen leadsDressing diskCarrying case Click image to enlarge Principle When two materials of different degrees of hardness of rigidity are forced against each other, one of the materials either yields or crumbles, while the other is unaffected. Thus a scale of relative hardness can be established on the basis of the ability of one material to scratch or deform another. This principle has long been used in the mineralogy field where it is known as the Mohs Hardness Scale (F. Mohs, 1820). Thus, the hardest material, diamond, is arbitrarily given a hardness value of 10, and other materials range downward through, for example, Corundum–9, Quartz–7, Apatite–5, Calcite–3, and Talc–1. Mechanical drawing pencil leads of available grades cover a range of useful organic coatings. The crumbling mode of failure is also an essential characteristic of the drawing leads, which is necessary for this application. The Pencil Hardness Gage/Gauge design allows the user to force pencil leads of increasing hardness values against a coated surface in a precisely defined manner until one lead mars the surface. Surface hardness is defined by the hardest pencil grade that fails to mar the painted or coated surface. The leads supplied with the Micro-Metrics Pencil Hardness Gage/Gauge, listed from softest to hardest, are:6B, 5B, 4B, 3B, 2B, B, HB, F, H, 2H, 3H, 4H, 5H, 6HThe leads are supplied in a carrying case that identifies each lead (individual leads may come without identification, or the identification mark may be difficult to read). Choosing and installing the eight leads most commonly used will allow the leads most appropriate to the surface(s) being tested to be always at the ready. Five small circular pieces of 400 grit carburundum paper mounted on a plastic dressing disk are provided to facilitate dressing the lead points while they are in place in the gage.
