Cutting Tools

YG-1 Tool Co. says it has changed the way you will look at general-purpose endmills. With YG-1’s superior substrate and YG-1’s proprietary coating on its GP endmills, the tools impart a fine surface finish on workpieces and extend tool life at a competitive price.

The RF 100 Diver family of high-performance, solid-carbide endmills from Guhring Inc. are capable of plunging and extreme ramping in alloy steel, cast iron and aluminum. The Diver is a variable-helix, 4-flute endmill with a special face geometry for drilling up to 2 diameters deep and ramping up to a 45° plunge angle.

Truly indexable finishing inserts have arrived with the new EDGE² spherical ballnose (SBN) system from DAPRA Corp. SBN inserts feature two usable cutting edges, delivering cost savings and high-quality finishes.

EHWA Diamond Industrial Ltd. offers its VT series of PCBN (polycrystalline boron nitride) indexable cutting tools. With the VT line of inserts, end users can achieve deeper depths of cut given the more robust method of cutting edge construction versus the industry standard brazed chip-style insert, according to the company.

Monolith extended-reach endmills from Ultra-Tool International Inc. have overall lengths up to 12" (304.8mm); runout at that length is 0.0003" (0.0076mm). SmoothFlute variable-helix, 5-flute, 45°-helix and roughing styles are available, as well as 2- and 3-flute tools for cutting aluminum.

Microcut Inc.’s line of miniature carbide endmills are from 0.002" to 0.125" (0.051mm to 3.175mm) in diameter and are available with long shanks and long reaches. The company offers AlTiN- and diamond-coated endmills and special rotary cutting tools, including thread mills, keyseat cutters, double-angle cutters, microdrills, spotting drills and dovetail cutters.

Rani Tool Corp. offers German-made PCD inserts with CB3 chipbreakers from Becker Diamond Tools. The chipbreaker has a semiserrated wave profile on the flanks of the cutting point, which increases the material-removal rate and produces short, controlled chips. The inserts are suitable for machining with flood coolant or minimal-quantity lubrication.

SwiftCARB offers a complete line of straight-shank and shell-mill indexable-insert corner rounders. According to the company, the tools increase cutting speeds and feed rates by 25 percent, and the tools’ inserts can be changed quickly, which enhances efficiency. The company stocks more than 70 radii, from 0.010" to 1" and from 1mm to 25mm.

Kyocera Precision Tools Inc. says positive-style inserts with its WP chipbreaker and a wiper cutting edge impart fine surface finishes at low cutting forces. The chipbreaker stabilizes chip conditions at low feed rates, controls excess chip breaking during high-feed and high-load machining and prevents tearing of the finished surface by controlling adhesion. The inserts are for machining steel and stainless steel and are available in a variety of CVD- and PVD-coated grades.

FMT beveling tools from Fastenal Co. are for cutting inside and outside bevels, pipe beveling, countersinking and generating radius paint edges. The spark-free, heat-free tools enable users to make head changes in 30 seconds. The electric FMT Bevel Mate is capable of bevel depths up to ½" (12.7mm), and the pneumatic FMT Bevel Mite is capable of bevel depths up to ¼" (6.4mm).
