RUKO Magnetic drilling machine Drilling depth Type and applications overview

Main application (^) Other application RUKO 189

Solid drills with Weldon shank (3/4") Can be used in all pillar and magnetic drilling machines with Morse taper in conjunction with RUKO holders no. 108 302-1, 108 303-1, 108 315, 108 316, RUKO EasyLock no. 108 312-1, 108 313-1, 108 314 or with direct Weldon shank holders such as RUKO magnetic drilling machine A10. • Slide the solid drill bit into the holder and tighten the hexagon socket screws. • Ensure that the "Solid 3S" solid drill bit is seated properly in the holder. • With the EasyLock quick-release holder, the solid drill bit is automatically locked in place. • Drill to size immediately,...

Further development of the cutting edge geometry Further development of the cutting edge geometry has resulted in significantly improved cutting behaviour, which has a positive effect on cutting performance and tool life. 1. Optimised cutting edge geometry for increased cutting performance and reduced cutting forces. 2. The rake angles are designed for universal use in various types of steel. 3. Improved chip evacuation thanks to U-shaped relief. The special geometry of the chip evacuation reduces the thermal load on the HSS core drill, as the heat generated during machining is largely dissipated...

Solid drill "Solid 3S" with Weldon shank (3/4"), CBN ground and 3 cutting edges, 30.0 mm The spiral-fluted 3-flute geometry ensures extremely high stability of the solid drill bit "Solid 3S" and thus prevents the risk of breakage of the cutting edges due to overstressing or jamming of the chips. The high stability significantly increases the service life of the "Solid 3S". This reduces operating costs. The "Solid 3S" enables precise spot drilling without centre punching and scribing. The solid drill bit is easier to regrind than core drills of the same diameter. Packaging: plastic tube The risk...

Core drill with carbide cutting edges and threaded retainer, 50.0 mm Ejector pin: Item no. 108 110 (0 6,35 x 123,0 mm) Adapter: thread M18 x 6 P1,5 Packaging: plastic tube

Can be used on all track drilling machines. The cutting geometry has been specially optimized for heavy duty chip removal from railway tracks, thus makes efficient use possible. Packaging: plastic tube

Packaging: plastic tube Centring: Position the ejector pin in the centre of the centre punch. The machine is now in the correct drilling position. Please switch on the magnet now. The cutting oil is discharged via the ejector pin by means of the automatic internal lubrication system and delivered to the cutting edges in optimum doses. In the final phase of drilling, the drill core is pressed out of the drill hole by the spring-loaded ejector pin.
