Drills & Drill Bits

The newly introduced MT Drill from Carmex is designed to drill, chamfer and thread mill a hole in a single operation. Constructed of solid carbide, the 2-flute drill/thread milling cutter, with 45-degree chamfering, reduces cycle times by combining operations and eliminating tool changes.

The idea of designing drills for higher feed rates by adding a third cutting edge is nothing new. However, due to the challenging chip evacuation, these tools have so far only been suitable for a few applications, such as machining cast iron. With a new design, the Hoffmann Group has now succeeded in harnessing the advantages of the three-flute drill for long-chipping steels and stainless steel materials.

Emuge Corp. has announced the launch of a carbide step drill program that features new drill–chamfer tools available from stock in real-time online at www.emuge.com/products/drills/ef-c-drills. Users can quickly and easily select from a full range of stock sizes, including the ability to order customized lengths available in less than 4 weeks.

Tungaloy is expanding its insert line for TungSix-Drill, the head-changeable drill, to include grade AH3135. TungSix-Drill is an indexable insert drill that incorporates double-sided, triangular inserts with six effective cutting edges.

ANCA offers the FCP4 high-production drill grinder (FCP4). Producing drills from 0.8 to 4mm with the new technology provides an exciting opportunity for drill makers, with important efficiencies and cost benefits by manufacturing a complete HSS drill on a single machine, according to the company. From a blank piece of raw material, the FCP4 grinds the flute, relief and point, producing a finished drill.

With a new reengineered design, the Seco Perfomax indexable insert drill delivers higher drilling parameters and longer tool life as well as exceptional chip control and evacuation. The drill's innovative features include new flute designs with special anti-friction surfaces and laser hardened fronts for added strength, stability and accuracy.

Arno Werkzeuge USA announces the introduction of their new SHARK-Cut multipurpose cutting tool platform for a range of turning applications. SHARK-Cut allows machines shops to use just one tool for four different machining operations including: facing, drilling, boring and turning.

Some good ideas can be made even better. Much better. This was certainly the case when Kennametal engineers took the strength and versatility of their proven KSEM modular drill system and combined it with the ease of use and low feed forces of its smaller companion drill, KenTIP, the company reports. The resulting fusion of these advanced holemaking technologies is the KenTIP FS, a 6 mm to 26 mm, 1.5 to 12 x D modular drill that's simple to use, produces good hole quality, and is tough enough to compete with solid-carbide drills across a wide range of materials.

Kyocera announced that it has developed a new line of indexable modular drills, Magic Drill DRV, to be used mainly for hole drilling in the machine tool business. Ideally suited for the automobile, aviation and medical device industries, the new indexable drills combine a chemical vapor deposition (CVD) coated insert on the outer edge and a physical vapor deposition (PVD) coated insert on the inner edge for the first time, enabling high-speed and high-efficiency processing.

With the new Seco Feedmax –P drill, manufacturers gain the potential to significantly boost holemaking performance for ISO P (steel), as well as cast iron, workpiece materials. The solid-carbide Feedmax –P drills can increase drilling productivity by up to 35 percent while also providing longer tool life due to the combination of the drill's new geometry and advanced coating.

Based on the previous success of PCD drill type »PS« during burr and delamination free machining of fiber composites – also in combination with aluminum – so-called stacks components – Lach Diamond developed the PCD drill type »PS-plus«.

Walter Surface Technologies announced the launch of its professional-grade, shock-resistant, extra-thick, polyethylene carrying case for the company's Super Speed Tip (SST) drill bits. Optimized from the original Walter metal index containers, the new highly visible orange polyethylene case offers increased durability and improved drill bit storage, according to the company.
