ROBERTSHAW 123122 UNIVERSAL SILICON CARBIDE DOUBLE HELIX SPIRAL DESI

UNIVERSAL SILICON CARBIDE DOUBLE HELIX SPIRAL DESI

The spiral design of the Double Helix Desi creates a more efficient, cleaner manufacturing process. While conventional raised spiral tools leave chips on the outer diameter of the part, leaving burrs and smeared surfaces behind, Double Helix Desi tools produce smooth, burr-free parts that are ready for finishing. Both EDM and SAW cutters are available in sizes from .020" to 2.5" in diameter.

This Silicon Carbide Double Helix Tooled Blade is designed to cut, thread and finish the concrete surface of helical piers up to 4 in. in diameter. The Universal Double Helix Tooled Blade can be mounted directly to a rotary hammer with a Rem SDS-PLUS shank.

This universal double helix spiral diamond sharpener enables you to sharpen long or short point tools for maximum versatility. The helix-shaped cutters feature more than 50 percent greater diamond exposure and provide faster cutting performance in the toughest materials like carbide, ceramic, and metal bond diamond.

(_)DESI(_) 85% left spiral helix design, eliminates the need for expensive and time-consuming reamers. The flutes are constant pitch.

Cast iron is extremely durable and possesses great thermal properties, but its major drawback is that it weighs more than most other construction materials. The cast iron that is formed into double helix spiral design (DSSD) resembles a slinky, which offers the stability of cast iron along with a reduced weight to aid in end-user comfort. This patented technology has the ability to flex and eventually break from impact. The spinning action of the drill bit creates stress on the end of the drill rod being pushed against by the DSSD coil. Once this stress becomes stronger than the diameter of the rod, it will create a tensile

These blades are Ideal for all stone materials, including marble limestone, travertine slate, onyx, terrazzo and concrete. The spiral micro-serrated blade channels water away from the cut line during the wet grinding process to prevent the accumulation of debris in the substrate - resulting in a cleaner cut each time. This is the highest quality brand of diamond blades by Robertshaw with patented features: Material: Double Helix Calibrations Range: 6? – 23'

The spiral double helix diamond blade cutter is capable of machining through a 75mm depth of concrete leaving a surface finish of 10 to 15 micro inches, (40 to 60 micro meters).
