Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 12.39mm FMH 21 mm reamer is ideal

21 mm reamer is ideal for production environments that demand consistent hole size and surface finish

1 mm corner radius supports durable fillets in mold features and delivers consistent edge quality with reduced risk of micro-cracking

The spiral flute design helps align and evacuate chips even in deeper bores

The WE524 end mill is ideal for mold and die tasks involving materials below 55 HRc

Length: Short overall length increases rigidity and minimizes deflection for precise pockets and slots

Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 12.39mm FMH 21 mm reamer is idealThe Toolex Reamer in a 12. 39 mm diameter is a carbide, straight shank finishing tool designed to bring pre drilled holes to exact size with repeatable, high quality results. Built for engineers, fabricators, and hobbyists, it combines an intermediate precision carbide edge (K10) with a left hand spiral flute and right hand cutting for predictable, controlled reaming. It follows ISO H5 tolerance and mirrors the DIN 212 B form for compatibility with
