Center Head for Combination Square

This Center Head is the essential geometry tool for your 4-piece combination set, engineered for the rapid and dead-on location of the center of cylindrical or round stock. While lesser tools struggle with slippage or inaccuracy on curved surfaces, our heavy-duty cast iron construction provides the "mass and dampening" required to lock into your workpiece for a perfect layout every time.

Why the PEC Center Head is a Shop Essential:

• Cast Iron Superiority: Built from premium cast iron, this head offers far greater "wear resistance and structural stability" than softer alloy alternatives.
• True-Running V-Groove: Features a precision-ground 90° internal V-angle that ensures your hardened rule bisects the center of any round stock with industrial consistency.
• Non-Slip Center Location: The essential tool for "accurately locating the center of cylindrical or round stock," making it a must-have for lathe work, shaft drilling, and fabrications.
• Precision-Ground Reference Surfaces: The "reference surfaces stay flat and true through years of heavy shop use," ensuring that your center lines are always referenced against a perfectly calibrated plane.
• Industrial Locking Bolt: Equipped with a knurled locking nut that provides a "non-slip grip on the hardened steel rule," preventing the head from shifting while you mark your zero.
• Shop-Hardened Durability: Designed to handle the "vibrations and wear" of a professional machining or woodworking environment without losing its dead-on accuracy.
