Description
The Robert Charles Deburring Tools Through Hole - Zero Flute - Imperial 100° - 1-1/4 in head diameter is a precision deburring tool engineered for fast, reliable finishing of through holes. It’s ideal for engineers, machinists, and production teams who need clean burr removal, precise chamfers, and light countersinking in a single pass.
Constructed from M35 HSS-E with cobalt, this tool blends exceptional wear resistance with high heat tolerance for demanding manufacturing environments. The zero-flute geometry minimizes chip clogging and reduces cutting resistance, helping you finish holes quickly while preserving edge quality.
- Zero Flute Geometry for Fast, Clean Deburring: The unique zero-flute design minimizes chip buildup and friction, delivering smoother edges and quicker finishing of through holes in a variety of materials.
- Rugged M35 HSS-E with Cobalt for Long Tool Life: Premium cobalt-enhanced high-speed steel delivers outstanding wear resistance and heat tolerance, meaning fewer tool changes and longer service between replacements.
- Imperial 100° Chamfer with 1-1/4 in Head Diameter for Consistent Results: Precisely matched geometry and scale ensure reliable chamfers and light countersinking in through holes, even on busy rigs and tight tolerances.
When you equip your shop with this deburring tool, you gain faster cycle times, fewer rework steps, and reliable, repeatable hole finishes. The combination of zero-flute geometry and cobalt-enhanced steel delivers consistent chamfers and clean edges, reducing post-process grinding and inspection time. Built for tough production environments, it helps you keep machines running smoothly and parts meeting spec, day after day.
