“The inserts, which are easy to handle and adjust, offer reduced cost per part along with high accuracy and repeatability,” adds Jacques Gasthuys, global automotive application engineer.

Unless you’re the most frequent of flyers, chances are you’ll be using your multi-tool of choice pretty frequently without having to pass through TSA. If you want a tool that can be as versatile as you, Big I Design has you covered. Its TPT Slide multi-tool is razor blade compatible — when you’re not flying, insert a blade and amp up the utility of your TPT, and when you are flying, slip that razor blade out and keep things simple.

Aluminum cylinder heads and engine blocks will be among the principal components to benefit, typically in automotive foundries or Tier 1/Tier 2 suppliers. By way of example, the cubing operation on a cast cylinder head would involve machining the camshaft face, inlet/outlet face and combustion face. Typical cutting data using M5Q90 might include a speed of 2,500 m/min. (8,202 sfm) and feed per teeth of 0.20 mm (0.008 inch). Users also benefit from high-precision coolant channels that provide the option for either emulsion or MQL application.

Victorinox’s classic red multi tools and pocket knives have been in EDC kits for generations — before everyday carry was even a thing. They’ve stood the test of time thanks to quality construction and usefulness in a small package, and the Jetsetter is no exception.

Its functionality is simple: it can tighten loose screws, pry things apart or open a cold beer at the end of a long day. CNC machined from a single block of 6AL4V Titanium, the Halifax is small, strong, lightweight and multi-purpose. It has the least of amount of included tools on this list, but for some of us, that’s more than enough.

This flight-friendly multi-tool eschews a blade, but it does pack seven useful tools into its 0.8-ounce frame, including scissors, a magnetic Phillips screwdriver and bottle opener. At less than $30, this helpful little tool is an easy “Add to Cart.”

M5Q90 cutter bodies are designed according to customer specifications, and therefore meet the requirements of high-productivity machining – the tool can operate in high-speed conditions in excess of 20,000 rpm. However, all cutter bodies offer the same design of tip seat, coolant channel, lead angle and rake angle. Inserts are always kept in stock.

TSA-friendly multi-tools tend to follow the design of 511’s EDT Multitool or the Gerber Shard (see below), but sometimes you can get away with something more akin to a fully built-out multi tool — like the Multi-Plier 600 Bladeless.

If desired, the cutter body tool life can be further extended in engineered solutions with PCD inserts protected by rows of carbide inserts, a configuration that also serves to increase the depth of cut capability. While the basic tool with PCD inserts offers 2–4 mm (0.079–0.157 inch) depth of cut in full engagement, this can be boosted to in excess of 4 mm (0.157 inch) using the engineered solution with protective rows of carbide inserts.

We’ve all had it happen: You’re shuffling along in the airport security line, bereft of your shoes and your dignity, when panic washes over you: Shit, I left my multi-tool in my bag!

Many of today’s multi-tools boast 10+ functions packed into a tiny profile, which is fine — but if you’re a fan of elegant design and don’t need a whole tool belt’s worth of tools in your pocket, the Halifax is right up your alley.

It doesn’t have to be this way. You can fly with a useful, badass multi-tool that won’t get you put on a watch list or require you to check a bag. Don’t believe us? Here are six great options for the next time you book a flight.

Distance between the bottom of the cut and the uncut surface of the workpiece, measured in a direction at right angles to the machined surface of the workpiece.

Rate at which metal is removed from an unfinished part, measured in cubic inches or cubic centimeters per minute.

Angle between the side-cutting edge and the projected side of the tool shank or holder, which leads the cutting tool into the workpiece.

The Shard is made from stainless steel with a titanium nitride coating for corrosion resistance, and includes seven tools in its 2.75-inch frame.

Weighing just an ounce, it’s an easy add to your keychain or unobtrusive if you slip it in your pocket — just don’t forget to check for it if you don’t have it secured on a key ring. The shard is sturdy, simple and a great gift for the handy folks in your life.

Capable of both face and shoulder milling, the M5Q90 is also suitable for many applications in the general engineering and aerospace sectors.

This multitool favored by the U.S. military features 14 tools, including tungsten carbide wire cutters, a ruler, scissors, a flathead and Phillips screwdriver, bottle and can opener and more. The body is built with black oxide coated stainless steel; it looks rugged, but may be prone to scratching with heavy use. Gerber says the bladeless version of their multi-tool is TSA-friendly, but if you have any doubts or catch a grumpy vibe from the TSA agents at the airport, you may want to put this in your checked bag — just in case.

Angle of inclination between the face of the cutting tool and the workpiece. If the face of the tool lies in a plane through the axis of the workpiece, the tool is said to have a neutral, or zero, rake. If the inclination of the tool face makes the cutting edge more acute than when the rake angle is zero, the rake is positive. If the inclination of the tool face makes the cutting edge less acute or more blunt than when the rake angle is zero, the rake is negative.

Engagement of a tool’s cutting edge with a workpiece generates a cutting force. Such a cutting force combines tangential, feed and radial forces, which can be measured by a dynamometer. Of the three cutting force components, tangential force is the greatest. Tangential force generates torque and accounts for more than 95 percent of the machining power. See dynamometer.

Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

To boost the first-stage roughing operation on newly cast aluminum parts for the automotive industry, cutting tool and tooling systems specialist Sandvik Coromant is introducing its M5Q90 tangential milling cutter. Designed to complete "cubing" (first machining of faces after casting) in a single operation without creating burrs, the new tool is fitted with PCD tangential inserts that provide a smooth and stable cutting action to lower power consumption and eliminate vibration. This concept ensures reliable performance, improved tool life, exceptional surface finish, high metal-removal rate and an increased number of parts per insert.

Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

Cutting tool material consisting of natural or synthetic diamond crystals bonded together under high pressure at elevated temperatures. PCD is available as a tip brazed to a carbide insert carrier. Used for machining nonferrous alloys and nonmetallic materials at high cutting speeds.

Along with its blade-compatible design, the TPT also features a removable pocket clip, bottle opener, multiple flathead screwdrivers, a mini pry bar, measurement cues and more. It’s sleek, sophisticated and strong — everything you could ask for in a multi-tool. At $80, it’s on the pricier end of the bladeless multi-tool spectrum, but if you’re willing to invest in this unique design, it should prove its worth in short order.

Ten tools in one is a bargain; 10 tools in one for $15 bucks is a steal. The EDT Multitool isn’t just cheap; it’s also tiny, at just over two inches long. 5.11 Tactical makes the most of this small package, fitting a standard 6mm hex wrench and flathead screwdriver, metric and imperial ruler, bottle opener, pry tool and wire stripper and more into its little tool.

The M5Q90 completes the Sandvik Coromant offer for machining aluminum automotive parts, complementing the M5B90, M5C90, M5F90, CoroMill Century/590 and M5R90 tooling solutions.

Loosely, any milling tool. Horizontal cutters take the form of plain milling cutters, plain spiral-tooth cutters, helical cutters, side-milling cutters, staggered-tooth side-milling cutters, facemilling cutters, angular cutters, double-angle cutters, convex and concave form-milling cutters, straddle-sprocket cutters, spur-gear cutters, corner-rounding cutters and slitting saws. Vertical cutters use shank-mounted cutting tools, including endmills, T-slot cutters, Woodruff keyseat cutters and dovetail cutters; these may also be used on horizontal mills. See milling.

You know you’re going to get pulled aside by TSA, and you’ll try to defend the two-inch blade on your Leatherman or Gerber that isn’t really that big of a deal, but you’ll still be faced with a choice (if you’re lucky): go back, check your bag and tool and re-do the whole security shuffle, or say goodbye to your multi-tool, pocket knife or other EDC implement with a blade.
