Horn Style Solid Carbide Small Bore Boring Tool, Through Coolant SD-MTR 5R0.2 L15 Internal Coolant Boring Bar
These Horn-style solid carbide micro boring bars of the SD-MTR series feature through-tool internal coolant, with specifications including 5R0.2 L15. Made of monolithic cemented carbide, they are designed for small-diameter internal boring and fit precision CNC lathes perfectly.
The internal coolant system delivers cutting fluid directly to the cutting edge, effectively removing heat and flushing chips. Precision-ground sharp edges guarantee high boring accuracy, excellent inner surface finish and stable dimensional precision in narrow small-bore environments.
Suitable for precision small-bore boring on CNC lathes, they greatly extend tool service life with superior cooling performance. They cut tool change downtime, improve machining yield and effectively boost overall micro-boring production efficiency.
