Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 3.79mm

Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 3.79mm sizes internal holes to a precise 3.79 mm using an intermediate precision carbide (K10) substrate. The straight shank clamps securely in standard toolholders, while the left-hand spiral flute and right-hand cutting promote efficient chip evacuation and repeatable hole finishes; tolerance is tight at ±0.003 mm in line with DIN 212 B style control.

• Carbide construction (K10) for long tool life: The intermediate precision carbide base resists wear and maintains dimensional stability through repeated use, delivering consistent hole sizing and reducing replacement frequency.
• Chip‑control geometry: left-hand spiral flute with right-hand cutting: The flute design facilitates efficient chip evacuation, minimizes built‑up edges, and helps produce reliable, smooth-hole finishes even in longer holes.
• Precise sizing with easy clamping: At 3.79 mm with a tight ±0.003 mm tolerance and a straight shank, this reamer stays square in the holder and delivers repeatable results across jobs.

Designed for a wide range of users—from engineers and shop floor technicians to hobbyists—this reamer provides dependable sizing and durable performance. The combination of carbide durability, controlled size, and straightforward setup helps streamline sizing operations, reduce tooling downtime, and improve hole quality across production runs and precision projects.
