Toolex Die Maker Reamer HSS-E Straight Flute SS M35 COB 5% - 4-2mm

Toolex Die Maker Reamer HSS-E Straight Flute SS M35 COB 5% - 4-2mm is a precision finishing tool built for die makers, machinists, and workshop technicians who demand tight hole tolerances and smooth finishes. This straight-flute, right-hand reamer uses cobalt-enriched HSS-E for exceptional wear resistance and reliable performance in metalworking applications.

With a 5% taper, it guides cleanly into the bore and minimizes chatter, while the straight flute supports efficient swarf evacuation for consistent hole diameter. The tool is ground to tight tolerances to help you hit target sizes consistently: D = ±0.05 mm, d = ±0.05 mm, L = ±1 mm, d1 = h8.

• 5% taper with straight flute for precise alignment: The taper guides the reamer into the bore smoothly, while the straight flute ensures consistent hole sizing and easy swarf removal, reducing rework in die-making operations.
• HSS-E (M35 cobalt) alloy for extended tool life: Cobalt-enriched steel provides superior hardness and wear resistance, helping the reamer stay sharp longer and deliver repeatable results across tougher materials.
• Tight tolerances for repeatability: D = ±0.05 mm, d = ±0.05 mm, L = ±1 mm, d1 = h8; these specifications ensure consistent hole dimensions across parts and minimize finish work and scrap.

This reamer helps you achieve clean, accurately sized holes with minimal downtime, improving workflow from drilling to finishing. Its durable HSS-E construction reduces tool change frequency, delivering consistent results across batches and materials. Choose this die-maker reamer to boost precision in die inserts, stampings, and fabrications, while maintaining a reliable, ready-to-use component in your shop.
