Solid drills with weldon shank (3/4") For use in magnetic-stand and pillar drilling machines with morse taper retainer. In connection with RUKO arbor holders no. 108 302 / 108 303 / 108 315 / 108 316, with RUKO EasyLock no. 108 312 / 108 313 / 108 314 or a weldon direct shank such as the RUKO magnetic-stand RS 5e / RS10 drill. Handling • Push Solid drill „Solid 3S“ into arbor and tighten hexagon socket screw firmly. • Check proper seating of Solid drill „Solid 3S“ in arbor holder. • With the EasyLock arbor, the Solid drill „Solid 3S“ gets automatically locked. • Drill to full dimension...

08 Solid drills „Solid 3S“ with weldon shank (3/4") and 3 cutting edges, cutting depth 30,0 mm The spiral-grooved geometry with 3 cutting edges ensures extremely high stability of the "Solid 3S" solid drill, thus preventing the risk of breakage of the cutting edges by overloading or jamming of the chips. Thanks to the high stability, the service life of the "Solid 3S" is considerably increased. This reduces the costs of use. The "Solid 3S" enables drilling to full dimension without centring or pre-drilling. The "Solid 3S" can be ground more simply than core drills of the same diameter....

Considerably improved cutting behaviour was attained by research into the cutting geometry, which has a beneficial effect on cutting performance and drill life. 1. Optimised cutting edge geometry for increased cutting performances and reduced cutting forces. 2. The effective cutting angles are designed for universal use in various sorts of steel. 3. Improved removal of chips thanks to U-shaped recesses. The specific geometry of the recess reduces the thermal load on the HSS core drill as the heat created in cutting is removed with the chips to a very great extent. 4. Reduction of the...

Product Information The RUKO core drills with Tecrona coating and hard metal cutting edges can be universally used in non-hardened steels and super alloys (materials with very high alloy percentages of Al,Ti, nickel like inconel, hastelloy, Inox, etc.). Technical data: Surface: Hardness: Thickness: Coefficient of friction: Advantages of the Tecrona coating The Tecrona coating is the ideal coating for all drilling works that stress the tool extremely. It adheres very well to the tool, where by the wear-resistant coating increases the surface hardness to approximately 4200 HV. The coefficient...
