The Straight-Shooter Take
A reliable speed square is the heartbeat of framing, rafter cutting, and circular saw guiding. Cheap stamped steel squares have painted lines that fade after two months in the sun and edges with rough burrs that throw off your 45-degree bevel cuts. SHALL's 2-piece set pairs a heavy 4mm thick rafter square with a 16-inch stainless steel combination square.
Fit, Finish & Mechanical Integrity
The speed square has CNC-machined edges that guide your circular saw shoe dead straight across 2x10 lumber. The laser-etched degree scales and common rafter pitch numbers are cut deep into the aluminum, so dirt and sawdust wipe off without losing readability.
- Saw Guide Lip: Thick 1/4-inch fence lip hugs timber edges securely without tipping
- Stainless Ruler: Resists rust and maintains crisp etched measurement markings
- Scribing Notches: Precision notches every 1/4 inch let you scribe parallel lines down long boards
Real-World Durability Check
- Pasture Shed Rafter Cuts: Cut 28 birdsmouth notches and plum cuts for a 12x16 run-in shed; all rafter tails matched up within 1/16 inch.
- Drop Test: Dropped the speed square onto gravel and packed clay; zero corner dings or bending.
- Saw Guide Track: Guided a 20V circular saw through 100 crosscuts of treated pine; fence edge showed zero blade gouging.
