July 20, 2020 - Kennametal, Pittsburgh, has introduced an expansion its solid carbide drilling portfolio, the HPX drill for high performance, large volume drilling in steel. Designed to quickly and efficiently punch holes up to 8 x D in any ISO-P steel material, the HPX drill provides up to twice the tool life and three times the productivity compared to competing products, even in dry or minimum quantity lubrication (MQL) applications.

Key differentiators

What makes the HPX drill the superior choice for Steel applications? The difference is in the design. Steels are used for a wide variety of automotive, commercial, and industrial applications, often in production volumes where maximum tool life and throughput is critical. Yet steel creates a high degree of mechanical loading during drilling operations resulting in forces that lead to rapid tool wear and chipping of the tool's more vulnerable corners. Kennametal has eliminated this failure point by applying a small corner chamfer and straightening the HPX drill's cutting edges. Together with the rounded margin lands running down the length of the flutes, this serves to stabilize the drill while reducing friction.

Built-up edge is another common problem when drilling alloy steels. The HPX drill's straight cutting edge helps eliminate some of this, but the real clincher is the drill's optimized edge preparation. This gentle hone further reduces the friction that leads to built-up edge, as do the tool's highly polished flutes. Couple that with a carbide grade designed specifically for steel—KCP15B—and a proprietary multilayer AlTiN coating, and the HPX drill sets a new standard for tool life in high-volume ISO-P drilling.

Lower forces, even better reliability

Special gashing on the HPX drill improves the chip formation and curls a smaller chip. The material specific HPX point geometry creates significantly lower cutting forces, which works great for machines with lower spindle capabilities, unstable cutting conditions, or unstable workpiece clamping. A continuous cross section makes the HPX drill more resistant against tool breakage, and the ultrahigh polished chip flutes ensure superior chip evacuation.

Manufacturers wishing to turn off their high-pressure coolant pumps in favor of dry cutting or MQL systems, efficient chip evacuation along with low-friction cutting is a must, and the HPX drill delivers on both counts. In fact, the drill comes equipped with a leakproof MQL interface that meets DIN 6535 and 69090-03 standards—no more special orders or in-house modifications.

November 14, 2019 - Hougen Manufacturing Inc., Swartz Creek, Michigan, has released three new RotaLoc Carbide Annular Cutter Kits which complement the ultra low profile HMD115 Magnetic Drill. There is a large master kit containing all the fractional sizes and two three-piece cutter kits. The cutters offer better performance in truck frames and harder materials. They can also be used in standard magnetic drills with an optional adapter.

May 28, 2019 - Titan Tool Supply Inc., Buffalo, New York, announced the introduction of its new line of precision Diamond and Borazon micro-finishing grinding pins. They are designed to meet an increasing demand for small precision ID grinding in industries such as ceramics, electronics, mold-making, and tool-and-die-making. A carbide shank provides added strength and precision, according to Titan Tool Supply.

The working ends of the pins are coated with either Diamond or Borazon. Three diameters are offered for use in small openings. These include 0.016 in. dia. with 500/600 grit; 0.020 in. dia. with 325/400 grit; and 0.024 in. dia. with 325/400 grit.

December 7, 2018 - Saint-Gobain Abrasives has introduced a new line of Norton Carbide Burrs designed for surface removal on demanding production runs with less changeovers. The hardness of a tungsten carbide substrate, stronger tooth formulation due to a decreased tooth wedge angle and numerous cutting edges, all provide the new Norton Double-Cut Carbide Burrs with a significantly extended life and better stock removal performance. For more information and to download a brochure, visit (Double-Cut Carbide Burrs | Norton Abrasives).

"Our Double-Cut Carbide Burrs can be used longer with fewer changeovers on challenging production applications as to compared to other double-cut burrs," said Patrick Carroll,

Norton | Saint-Gobain Abrasives Senior Product Manager. "Operators will achieve high stock removal and smaller, granular chip-break on hard-to-grind work pieces."

The Norton Double-Cut Carbide Burrs are ideal for efficiently removing surface stock and weld splatter, deburring and chamfering applications, along with medium to light cleaning. Specially designed tool geometries are ideally suited to meet the growing demands for stainless steel, steel, cast steel and composites applications. The new burrs perform well at higher temperatures and can be used longer than high-speed steel tools.

The versatile Carbide Burrs can be used on handheld tools such as the new Norton Pneumatic Die Grinder or on automated CNC machines. The Norton Carbide Burr line encompasses thirty different tools and is offered in seven types including; SA Cylindrical without End Cut, SB Cylindrical with End Cut, SC Ball-Nosed Cylindrical, SD Ball Shape, SF Ball-Nosed Tree, SG Tree with Taper, and SL Ball-Nosed Cone style. A kit is also available, including the most popular five burr types for smaller job requirements.
