Description
Drillco 427N141 .652 Spiral Flute 1/2 Shank Nitro Construction Reamer is engineered for heavy-duty reaming in structural steel assembly fabrication. The Nitro surface treatment provides a hard, protective layer that increases hardness without brittleness, while the black and gold finish ensures maximum lubricity. Its tapered point allows smooth entry into misaligned holes for precise and efficient reaming. Made from premium grade cobalt HSS, this reamer can drill harder materials approximately 30% faster than standard HSS. The 3-flats reduced shank ensures a secure grip, and the shorter screw machine length adds rigidity to minimize breakage during operation.
Features:
- Nitro surface treatment increases hardness and lubricity
- Premium grade cobalt HSS for harder materials and faster drilling
- Self-centering 135° split-point reduces walking and thrust
- Black and gold finish provides high lubricity
- Short screw machine length increases rigidity and reduces breakage
- Tapered point for smooth entry into misaligned holes
- 3-flats reduced shank for secure, non-slip chuck grip
Benefits:
- Enables efficient reaming in challenging materials
- Durable construction for prolonged industrial use
- Improved chip removal and cutting efficiency
- Reduces risk of breakage under heavy loads
