Step that prepares a slug, blank or other workpiece for machining or other processing by separating it from the original stock. Performed on lathes, chucking machines, automatic screw machines and other turning machines. Also performed on milling machines, machining centers with slitting saws and sawing machines with cold (circular) saws, hacksaws, bandsaws or abrasive cutoff saws. See saw, sawing machine; turning.

It’s natural for technology to get smaller, more powerful, and more affordable. A computer occupied the size of an entire room 50 years ago. Now it fits in the palm of your hand and can literally communicate with satellites. Televisions have gone from heavy, bulky appliances to paper-thin display units too. The SDS Ultra follows a similar trajectory, fitting an entire drill kit in the size of a fountain pen, while still being versatile and affordable… besides, with its Benchtop Press accessory, the SDS Ultra holds the mantle of being the world’s smallest vertical drill machine too!

• More than 250 new Hertel spotting drills and combined drill and countersink tools join the hole-making tool line. With 60ÌÜÅÁ, 90ÌÜÅÁ and 120ÌÜÅÁ point geometries, the HSS and cobalt tools can meet a wide range of application requirements.

Speaking of traditional drill machines, the SDS Ultra even comes with an impressive accessory in the form of the Hedgehog Benchtop Press – a tiny tabletop chassis that turns your handheld drill into a professional vertical drill. Designed for the kind of precise drilling where handheld use would prove to be difficult, the Benchtop Press lets you dock your drill pen into its design, which clamps onto a tabletop surface, giving you a lever-operated vertical drilling machine that allows you to drill holes with utmost precision and accuracy. Made from a high-grade aluminum alloy, the Benchtop Press even comes with a drill-bit holder built into its spine, letting you store and access the 10 drill bits on the fly. It also gets its Hedgehog moniker from the fact that the vertical drill holder can change angles, pointing in any direction (sort of like the spines on a hedgehog). Apart from merely adjusting the height of the drill, the Hedgehog Benchtop Press lets you rotate the drill as much as 180°. “Users can switch the drill angle to +/- 15, 30, 45, 90, or 180 degrees are used for tasks such as polishing metal objects, sanding different shapes, and sanding metal pieces,” says the team at Arrowmax.

Tool that cuts a sloped depression at the top of a hole to permit a screw head or other object to rest flush with the surface of the workpiece.

Available in two major types: tungsten high-speed steels (designated by letter T having tungsten as the principal alloying element) and molybdenum high-speed steels (designated by letter M having molybdenum as the principal alloying element). The type T high-speed steels containing cobalt have higher wear resistance and greater red (hot) hardness, withstanding cutting temperature up to 1,100º F (590º C). The type T steels are used to fabricate metalcutting tools (milling cutters, drills, reamers and taps), woodworking tools, various types of punches and dies, ball and roller bearings. The type M steels are used for cutting tools and various types of dies.

• Added versions of workhorse M42 cobalt roughing end mills include new sizes, coatings and fine and coarse roughing geometries.

Machining grooves and shallow channels. Example: grooving ball-bearing raceways. Typically performed by tools that are capable of light cuts at high feed rates. Imparts high-quality finish.

The handheld electric drill pen comes with an aluminum outer body that features an OLED display, a button to power the drill and another to cycle through its RPM settings, and four strategically located shadow-less LED lights that help illuminate your drill-zone so that you can clearly see exactly where you’re drilling with no shadows or obstacles. The single-button RPM control button lets you access the SDS Ultra’s four RPM settings, going from 300RPM for tougher materials like aluminum, to 600RPM that works easily on softer plastics and wood. The built-in 500mAh battery gives the SDS Ultra hours worth of usage, allowing you to drill over 500 holes on a single charge.

Stainless steels possess high strength, heat resistance, excellent workability and erosion resistance. Four general classes have been developed to cover a range of mechanical and physical properties for particular applications. The four classes are: the austenitic types of the chromium-nickel-manganese 200 series and the chromium-nickel 300 series; the martensitic types of the chromium, hardenable 400 series; the chromium, nonhardenable 400-series ferritic types; and the precipitation-hardening type of chromium-nickel alloys with additional elements that are hardenable by solution treating and aging.

Process of both external (e.g., thread milling) and internal (e.g., tapping, thread milling) cutting, turning and rolling of threads into particular material. Standardized specifications are available to determine the desired results of the threading process. Numerous thread-series designations are written for specific applications. Threading often is performed on a lathe. Specifications such as thread height are critical in determining the strength of the threads. The material used is taken into consideration in determining the expected results of any particular application for that threaded piece. In external threading, a calculated depth is required as well as a particular angle to the cut. To perform internal threading, the exact diameter to bore the hole is critical before threading. The threads are distinguished from one another by the amount of tolerance and/or allowance that is specified. See turning.

Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.

• Hertel turning insert products, including HC115T turning grade for steel, HP410T/HT410T grades for nonferrous materials, and HP510T grade for high temperature alloys.

In addition we've also added our next generation of insert grades which include HC1250T, HP225T, HC405T and HC315T. These new grades and chip breaker geometries work across a wide variety of applications, including steel, stainless steels and cast iron.

Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.

Designed by the folks at Arrowmax, the SDS Ultra follows their existing lineup of award-winning handheld tools, including handheld electric screwdrivers and polishing/engraving tools. It’s safe to say they’ve mastered the art of making otherwise bulky hardware tools portable and handy, with the SDS ULtra quite literally looking and feeling like a pen, but housing a motor on the inside capable of hitting rotational speeds of 600RPM with a torque of 2.3 kgf cm. This means, as compact and lightweight as the SDS Ultra is, it’s easily capable of drilling through regular materials such as wood, acrylic, plastic, and PCBs, as well as tougher materials like aluminum and even everyday coins made from alloys of copper, nickel, and zinc.

Drill Bit Placement – Has dedicated slots for ten drill bits so that you can easily pick and swap the bit you need right then and there.

MSC Industrial Supply Co. is significantly expanding its Hertel line of metalworking products.

The SDS Ultra comes along with its army of 10 titanium-coated high-speed steel (HSS) drill bits that go from as small as 0.6mm to 2.2mm in diameter. The titanium-coated-steel helps the bits have a high wear resistance and low friction coefficient, making them effective on hard materials like metals while keeping them sharp and durable for years, and the SDS Ultra’s special drill-fastening design helps you easily and rapidly load and unload drill bits in an effective manner… much faster than how you would on a traditional drill machine.
