The Baer Circular Die HSS BSP Left Hand delivers reliable external threading for 1 x 11 pipe and cylindrical stock. Machinists and fabricators choose it when they need clean left-hand BSP threads without frequent tool changes.

• Material: High-speed steel construction that maintains sharp cutting edges through repeated use on steel, brass, and similar metals.
• Thread Specification: British Standard Pipe (BSP) profile cut in the left-hand direction at 11 threads per inch.
• Size and Form: 1-inch nominal diameter circular die designed to fit standard die holders or stocks for controlled rotation.
• Cutting Geometry: Precision-ground teeth that produce accurate thread flanks and smooth engagement with mating fittings.

Users gain consistent thread quality on pipe assemblies, hydraulic lines, and repair jobs where left-hand BSP threads are specified. The durable HSS body reduces downtime from tool wear while the circular design allows straightforward setup and even cutting pressure.
