A new  Micro Drill Analyzing Microscope from Titan Tool Supply, Inc. inspects the geometry, finish, and accuracy of new and re-sharpened miniature carbide drills as small as 1/8” diameter. Ideal for inspecting the quality of drills used in micro-manufacturing and micro-electronics, it provides a single-purpose, low-cost alternative to optical comparators and toolmakers microscopes, which entail a significant amount of set-up time, according to the company. Titan Tool’s Model MDGA features a 30X magnification lens with a special reticle, two-position viewing, and 360-degree rotation of the drill in a precision collets holder to allow for complete inspection without refocusing or other adjustments. A travel rack and pinion brings the drill into focus.

The new Model MDGA analyzer from Titan Tool enables the user to inspect:

• Point Centrality
  
• Hook
  
• Back Taper
  
• Point Angle
  
• Primary Relief Angle
  
• Secondary Relief Angle
  
• Web Taper and Web Thickness
  
• Chisel Edge Angle
  
• Lip Height
  
• Cutting Drill Edge Irregularities and Drill Irregularities
  
• Drill Point Finish
  
• Body-to-Shank Concentricity

The new Titan Micro Drill Geometry Analyzer was designed so that two different views in two different planes of the drill can be inspected without changing set-up. View one inspects the side of the drill, capturing all angles and most other adjustments. View two inspects the end of the drill to capture width, thicknesses, flare, and other factors. The two different views are obtained by rotating the drill holding fixture 90 degrees on its own axis.

The new inspection tool measures 9-1/2” x 1-1/2” x 2” and weighs only 1-lb., 6-oz. It is equipped with two 4mm diameter Allen head screws for mounting the microscope in a bracket holder, if desired. Shank drills smaller than 1/8” diameter can be inspected if a spacer (not provided) is used.
