The MILWAUKEE 300mm Magnetic Combination Square is more precise and delivers ultimate versatility. The durable stainless-steel draw bolt provides a strong blade hold, while the precision-etched blade slides easily. A larger head increases contact area for more precise measurements, and the machined 45° and 90° working surfaces ensure accurate squaring and angle transfer. With rare-earth magnets securely fastened to the head, this square makes working with conduit and metal materials easier. The tool features a High Visibility SHARPSITE vial for quick level checks, stores a Scribe Pin in its head for on-tool marking, and combines those layout functions into a single versatile instrument. The 300mm Magnetic Combination Square is backed by a Limited Lifetime Warranty. Material: Stainless Steel.
