Founded in 1880, The L.S. Starrett Company is globally recognized as a premier leader in the manufacturing of precision measuring tools, metrology systems, and saw blade technology. Delivering industrial-grade accuracy and structural longevity, Starrett products serve critical roles in aerospace, automotive, machining, and heavy manufacturing sectors worldwide.

PRECISION MEASURING TOOLS

  • Micrometers - Available in mechanical digital, vernier, and electronic configurations. Starrett micrometers feature balanced frame designs, crisp graduations, and satin-chrome finishes that resist rust and glare. Renowned for their carbide faces and smooth micro-lapped spindles.

  • Slide Calipers - Includes dial calipers, electronic digital calipers, and traditional vernier calipers. Engineered from hardened stainless steel, providing smooth slider movement, depth-measurement rods, and IP67-rated protection against coolant, water, and shop dust.

  • Combination Squares - Invented by Laroy S. Starrett in 1878, the combination square remains an industry standard. Featuring hardened, photo-engraved steel blades and precision-machined cast iron or hardened steel heads for squareness and angular verification.

  • Dial Indicators & Gauges - Engineered with high-precision gear trains and jeweled bearings for low friction. Includes test indicators, plunger indicators, and magnetic bases designed to measure structural deviation, runout, and alignment with micro-inch repeatability.

PRECISION SHOP TOOLS & FIELD GAUGES

Designed for specialized technical assessment on the production floor, these specialized instruments verify specific spatial metrics.

  • Bore & Internal Diameter Gauges - Electronic and mechanical split-ball or three-point contact systems optimized for precise cylinder and blind-bore measurement.

  • Height & Depth Gauges - Multi-functional columns utilizing high-precision encoders to capture vertical distances, steps, and interior contours with extreme accuracy.

  • Thread & Pitch Gauges - Critical checking profiles for validating industrial thread forms, pitches, and micro-clearances.

  • The Starrett Precision Standard - All hand measuring tools are calibrated against strict internal benchmarks traceable to national standards, ensuring unmatched linear consistency across global manufacturing frameworks.

INDUSTRIAL SOLUTIONS

INDUSTRIAL SYSTEMS & SAW TECHNOLOGIES

METROLOGY SYSTEMS

For high-throughput industrial inspection and automated quality control, Starrett supplies comprehensive non-contact and contact optical solutions.

Optical Comparators Heavy-duty profile projectors combining precision mechanics, high-performance optics, and digital readouts. Ideal for clear, two-dimensional silhouette inspection of complex profiles, stampings, and fasteners.

Vision & Video Inspection Systems Multi-sensor video measuring systems providing automated 2D and 3D data acquisition. Utilizing high-resolution cameras, telecentric optics, and advanced software to inspect microscopic features with rapid cycle times.

BANDSAW BLADES & POWER TOOL ACCESSORIES

Starrett is a global leader in high-performance cutting technology, manufacturing robust blades designed for extreme structural metalworking and general purpose wood cutting.

Bi-Metal Bandsaw Blades: Featuring high-speed M42 or M51 cobalt steel teeth electron-beam welded to tough alloy backing steel. Engineered to handle structural steels, alloys, and exotic solids.

Carbide Tipped Blades: Formulated for cutting abrasive materials, high-nickel alloys, titanium, and large aerospace metals where traditional bi-metal options wear rapidly.

Hole Saws & Hand Tools: Deep-cut bi-metal hole saws, diamond-grit hole cutters, reciprocating saw blades, and premium hacksaw frames suited for electrical, plumbing, and mechanical trades.

GRANITE SURFACE PLATES

Serving as the structural foundation for all precision layout and inspection operations, Starrett granite plates provide an exceptionally flat, temperature-stable surface.

Crystal Pink® Granite Starrett's signature granite line possesses a high quartz content, providing superior wear resistance, low water absorption, and minimal temperature reactivity. Available in Grades AA (Laboratory), A (Inspection), and B (Shop).

Custom Accessories Includes durable steel support stands, surface plate cleaners, precision parallels, v-blocks, and straight edges designed to preserve and expand plate functionality.
