The 13-inch Magic Keyboard uses the same scissor switches that Apple uses across its product lines (my kingdom for mechanical low-profile switches, Apple—you of all manufacturers could make it happen). They're perfectly functional if not a little mushy to type on.

In order to do so, please follow the posting rules in our site's Terms of Service.  We've summarized some of those key rules below. Simply put, keep it civil.

The production of deep holes can be achieved with many different processes. To create a high-quality final product and keep costs under control, shops must be able to get accuracy, repeatability, and good surface finish while maintaining predictable tool life. Selecting the most appropriate tool for the job and implementing the right operating procedures can improve this difficult operation, making it productive and profitable.

Gundrilling is a deep hole drilling process that uses a long, thin cutting tool to produce holes at high depth-to-diameter ratios. Gundrilling is typically effective in diameters from 1 – 50 mm [~0.04 – 2.00 in]. A gundrill differs from a conventional twist drill by its unique head geometry; a standard gundrill has a single effective cutting edge that removes chips as it advances into the workpiece.

For gundrills, BTA and Ejector drilling, Triumph Tool proudly represents botek, the world market leader in the field of single flute gundrills. Please contact us to learn more about how botek’s over 40 years of experience in deep hole drilling and applications can benefit you.

Not having the iPad Pro that attaches to (I opted for the nano-textured model which won't ship till June), I did what any hardware nerd would do—I grabbed the previous-gen Magic Keyboard from my current iPad Pro and did a side-by-side comparison

Deep hole drilling is the process of machining holes with a depth to diameter ratio of greater than 10:1. Below, we’ll explain 5 deep hole drilling tools and technologies: gundrilling, BTA drilling, ejector drilling, bottle boring tooling and counter boring tooling.

Advantages of multi-edged counterboring tools include elevated feed rates and improved workpiece quality. Constant wall thickness is often a desired result, which can be achieved by way of tool guidance in the tube (tool follows the pilot hole).

Metal-working fluids are an important part of any deep hole drilling operation, for more information visit our blog “Understanding Metal-Working Fluids for Deep Hole Drilling Operations”.

But while typing action is essentially the same for both cases, the new row of function keys is brand new. You get all kinds of handy things like brightness, volume, and media control, just like you do on any other Apple computing device. It's a nice bit of synergy and a welcome bit of practicality.

I was surprised to see that the new Magic Keyboard defaults to a more aggressive viewing angle than the previous-gen. Granted, the mid-cover hinge will let you adjust the angle however you like, but there's definitely a "natural" angle that the cover opens to. I'll have to get a new iPad Pro in hand to see how this actually plays out, though, if it really is an improvement.

One last thing that surprised me was the new, rectangular hinge. It's exposed aluminum (the previous gen is covered by the neoprene cover) and gives additional laptop vibes. It's also more grabbable than the previous gen.

A tool that is used to enlarge existing bores by removing stock. This type of tooling is typically used on BTA-equipped deep hole drilling machines.

The result is a palm rest that's vastly improved over the previous generation. While typing on the Magic Keyboard for iPad Pro is never going to be as comfortable as a full-sized desktop keyboard, it does a much better job of replicating the experience of typing on a MacBook Pro. You can rest your hands more naturally without scrunching your fingers.

Why not just pop my last-gen iPad Pro on there to try it out? The redesigned iPad Pro no longer has the magnets in the same spot, so the magnets in the cover have changed as well. You can slap the old iPad Pro on the new case, but it sits at a decidedly rakish angle, not really great for evaluating anything.

BTA drilling heads are threaded and are mounted onto long drill tubes. BTA drilling heads have multiple cutting surfaces to remove chips efficiently, exhausting them using high-pressure metal-working fluid through holes in the tool head, then out the drill tube and through the machining spindle. BTA tooling is available in brazed or inserted carbide configurations.

The new Magic Keyboard feels decidedly like a premium Apple accessory. The materials are impeccable, the design is smart and functional, and (I'm assuming, given that I don't have an iPad Pro to test it with) it will just work without any additional futzing required.

For Bottle Boring and Counter Boring tools, we are proud to represent BGTB GmbH, a German manufacturer specialized in the conception, design and manufacture of complete bottle boring systems for machining non-cylindrical inner contours.

A tool which is used to machine an internal profile within the length of a bore using a cutting insert, which is extended and retracted with CNC capabilities on a BTA-equipped deep hole drilling machine.

The 13-inch Magic Keyboard technically has more space to work with, barely, over the 12.9-inch Magic Keyboard. However, Apple used the redesign opportunity to add a larger trackpad, shifting the keyboard (now with a row of function keys) a bit more towards the hinge.

The gundrilling process can drill deep holes beyond what is possible with conventional machinery and tooling, such as twist drills, by using high pressure coolant for clean chip exhaust, even at extreme depths.

The metal-working fluid is fed through an annular space between the drill tube and an inner tube (double-tube system). The fluid exits from the side of the drilling head, flows over it, and then flows back into the inner tube along with the chips. Some of the fluid is introduced into the inner tube ring nozzle. The resulting underpressure at the chip mouth enables backflow (the ejector effect). An ejector cooling-lubricant feed system is required to generate the ejector effect.

This system is a variant of the BTA drilling system. Ejector deep-hole drilling is mainly used on conventional machine tools and machining centers; however, unlike BTA deep-hole drilling, there is no sealing to prevent the exit of the metal-working fluid at the workpiece. This drilling system can thus be used if it is not possible to seal the metal-working fluid circuit, e.g. for oblique boring or discontinuous workpieces. Drilling depths of up to 100 x D are possible with this process.

The first, most obvious, difference between the two models is the finish. The new Magic Keyboard for iPad Pro (M4 chip) is built with an aluminum palm rest. The previous-gen Magic Keyboard's palm rest is soft matte neoprene like the cover. It's perfectly serviceable but in no way screams that it's a premium accessory.

BTA stands for Boring and Trepanning Association and is also sometimes referred to as STS (single tube system) drilling. BTA drilling is a deep hole drilling process that uses a specialized drilling tool on a long drill tube to produce deep holes with a typical diameter of 20 mm [~0.80 in] and larger, and depth-to-diameter ratios of up to 400:1.

I'll admit, previous generations of the Magic Keyboard (and Keyboard Folio, may it rest in peace) underwhelmed me. For their premium prices, they didn't offer any more (and sometimes less) than third-party accessories.

If you're looking for the best portable keyboard case for your new iPad Pro, Apple has finally delivered a true winner that's worth its $299-$349 price tag. Pick one up or find out if it's in stock near you on the Apple website.
