Tungsten Steel SBPR5 20L R0.1 4mm 6 Stainless Boring Tool Customizable OEM Inner Hole Machine

Product Selling Points

This SBPR right-hand small-bore boring tool is forged from solid tungsten carbide with high-aluminum nano coating. Available in 4mm and 6mm shank sizes, it machines steel and stainless steel within HRC50, ideal for micro inner boring on Swiss-type CNC lathes.

Precision-lapped cutting edges with optimized anti-vibration structure ensure stable chatter-free boring in tiny bores. The high-aluminum coating boosts wear and heat resistance, achieving tight dimensional tolerance and superior surface finish for hardened workpieces.

The high-rigidity integral carbide shank delivers reliable performance in micro-diameter boring operations. Prolonged tool life cuts tool-change frequency and downtime, effectively improving mass production efficiency of precision miniature metal parts.
