These Horn-style solid carbide micro boring bars belong to the SD-MPR series with through-tool internal coolant, available in specifications like 6R0.2 L15/L30. Made of monolithic cemented carbide, they are engineered for small-diameter internal boring and perfectly match precision CNC lathes.
The internal coolant system delivers cutting fluid straight to the cutting zone, efficiently dissipating heat and flushing away chips. Precision-ground sharp edges ensure high boring accuracy, excellent inner surface finish and stable dimensional precision in confined small-bore spaces.
Ideal for precision small-bore boring operations on CNC lathes, they deliver significantly extended tool life thanks to superior cooling. They reduce tool change downtime, improve machining yield and effectively boost overall micro-boring productivity.
