TOOLS FOR METAL CUTTING MAIN CATALOG

A craftsman does not want an 8 mm drill. He wants a precise 8 mm hole in the workpiece.

RUKO precision tools Our passion and unbridled love to detail is in every single one of them Work processes are changing, the time frames for the realization of projects are becoming ever tighter and the expectations of clients for a perfect and error-free result are constantly growing. Meeting the increasing challenges in trade and industry with the right tools forms the basis for every RUKO development. Whether working with hand-held tools or in series production on stationary systems – every drill, every countersink, every threading tool and every burr is at the end of the process chain and...

Our fascination for solutions for metal cutting drives us. It turns metal into not just a tool, but a precision tool that bears the name of RUKO.

Or how to perfect perfect tools

Invented to make your work a little better every day, the ULTIMATECUT premium line guarantees perfect work results in industry and professional trades. Twist drills, step drills, countersinks – with innovative FLOWSTEP® tip, specially developed FLOWSTEP® cutting geometry and countersinking with four instead of three cutting edges. For more efficiency and less rework. For more speed with up to three times faster work results. With high wear resistance for significantly more tool use.

Tuning for drilling, sinking and cutting RUKO's own coating Best of the best: Our RUnaTEC coating impresses with absolute top values: In the areas of friction loss, nanohardness, the ability to work at extremely high cutting speeds up to a maximum of 1,100 degrees Celcius and a tool life that is up to 16 times longer than uncoated cutting tools.

Coated tools may be recognizable at first glance, but they are far more than just cosmetics. This is because, as in motor racing, the aim of coatings is to maximize the performance and durability of each tool. This includes, for example, a significant reduction in friction, the ability to drill faster and more precise holes at higher cutting speeds, but also to guarantee consistently high machining quality over the entire service life of the tool thanks to even wear. Another advantage is that the tools need to be replaced less frequently, resulting in less downtime and more efficient machining....

The origin of the RUKO application color guidance system is based on the three major application fields of metal, concrete and wood. The metal application field consists of structural steel, stainless steel and high strength steel. The other areas include concrete and wood; collectively providing the five primary application groups within the RUKO application color guide system. e.g. structural steel, e.g. stainless steel V2A, e.g. steel (N/mm2) < 1300, e.g. stone, e.g. softwood, steel (N/mm2) < 900 steel (N/mm2) < 1100 Titanium alloyed concrete chipboard Heavy-duty high speed steel for drilling...

Twist drill with FLOWSTEP® tip FLOWSTEP® tip Precise centering = no slipping when positioning. Time saving due to faster drilling = more holes drilled in the same time. Power-saving drilling = more holes without a break.

3-surface shaft No slipping in the drill chuck, therefore optimum power transmission. No more retensioning in the drill chuck, making work simple and uncomplicated. black bevel The black bevel increases wear resistance and at the same time reduces cold welding at the groove edges.

Point grinding and pointing according to DIN 1412 N Shape N: Helical point normal ground Application: For all normal drilling work in steel, non-ferrous metal and plastic. The point angles depend on the ease with which the materials can be cut. Advantages: Powerful main cut, resistant to impact and lateral forces. Simple manual grinding possible. Disadvantages: Broad cutting edge requires considerable pressure. Shape A: Cut chisel edge Application: For all normal drilling work using drills with a strong core, for drilling into solid materials with larger drill diameters. Advantages: Good centering...

This starts with the point grinds and the different helix and point angles, which have a significant influence on the precise drilling behaviour. This also includes the differently designed flute profiles, which optimise chip pick-up and removal and thus prevent the drill bit from annealing or even breaking. Or the core thickness, which plays a decisive role in the stability of each twist drill. This results in twist drills with individual class. For traditional craftsmanship, for use in industry or for tasks that require highly specialised solutions. RUKO specialists
