Description
High speed steel.
The spiral fluted 3-cutter geometry of the Ruko Core Drill Bit Solid 1081212 ensures extremely high stability of the “Solid 3S” solid drill, thereby preventing the risk of breakage of the cutting edges due to overloading or jamming of the chips.
The risk of breaking the solid drill up to Ø 15.0 mm is significantly lower compared to core drills of the same diameter. However, you’ll need cooling. Meanwhile, the high stability increases the service life of the “Solid 3S”, thus reducing operating costs.
The “Solid 3S” also lets you drill precisely without centre punching or marking. In addition, the solid drill is easier to regrind than core drill bits of the same diameter.
