Toolmakers’ Series Reticles

Description

• 176-126 TM-RETICLES Broken Cross

  This refers to a 90° broken cross-hair reticle, a standard accessory for Mitutoyo Toolmakers Microscopes, used for general measurement and alignment tasks.

• 176-111 TM-RETICLES Concentric C

  This is a concentric circle reticle used for measuring circular features or checking concentricity. Specifically, the 176-111 model has concentric circles with 0.05mm increments and a maximum diameter of 4mm.

• 176-135 TM-RETICLES Concentric C

  This also denotes a concentric circle reticle, similar in function to the 176-111 but likely with different specifications for the concentric circles (e.g., different increments or maximum diameter), although detailed specifications for this particular number are not provided in the search results.

• 176-114 TM-RETICLES 60-100 Angle R

  This describes an angle reticle, designed for measuring angles. While the exact pattern isn’t detailed, “60-100 Angle R.” suggests a scale for measuring angles within a specific range, possibly a 60-degree angle or a pattern involving 60 and 100 unit markings for angular measurements.

  Product	What it does
  176-126 — Broken Cross-hair Reticle 90°	Cross-hair with a small gap at the center so the feature isn’t obscured when you line it up. Quick centering of holes, pins, and shaft ends Easy edge alignment for perpendicular features Gap keeps the exact intersection visible while focusing
  176-111 — Concentric Circles Reticle (Metric)	A stack of metric-spaced circles that helps you center round parts and estimate diameters at a glance. Fast centering of bores and pins on the stage Quick visual check of roundness and runout Metric labeling simplifies notes and reports in mm
  176-135 — Concentric Circle Reticle (Inch)	Same concept as the metric version, but marked in imperial units for inch-based drawings and specs. Easy centering of holes/pins with familiar imperial steps Great for quick diameter estimates and fit checks Reduces conversion when documenting in inches
  60° Angle Reticle	Fixed 60° reference used to check chamfers and thread forms (UN/metric threads are 60° included). Align tool edges, chamfers, and thread profiles to a known 60° wedge Speeds yes/no angle verification without doing XY trig Rotate the eyepiece to match part orientation, then read/compare

  Notes: Reticles are etched glass inserts for TM-Series eyepieces. Focus the reticle first (diopter),
  then focus the part. Reticles can be rotated in the eyepiece to align with your feature. The last item’s SKU
