What is a DIN number?

There are various sets of standards in the tool world.  In America we have The American National Standards Institute or ANSI for short.  On a global level, there is the International Organization for Standardization, or ISO.  Since this is a blog about specifically German made tools we will look at the German version: DIN.

DIN stands for Deutsches Institut Für Normung or German Institute for Standardization in English.  They have been operating for literally 100 years and have always been highly regarded in the standards community.  Though the name implies an exclusively German operation, the DIN standards have been adopted across the world and influenced many other standards organizations including the ISO.  The best example of this is the DIN standard 476 from 1922 introducing the A sizes of paper which would later become ISO 216 in 1975.

Though it may seem obvious, it bears questioning why we need standardization. Many standards, including DIN, are completely voluntary, but it is beneficial to use standards to prove that you are manufacturing something to the highest quality and uniformity.  DIN standards are developed by experts in the respective fields and are reviewed every five years to ensure that they are up-to-date and still “State of the Art.”  They are used for a wide range of things too, from metric fasteners to car stereos.

You will see many examples of DIN standards amongst the pages of the KC Tool website.  For instance, this Gedore Engineers’ Hammer has two standards it lives by, one with the hickory handle and the other with the forged hammer head.

The best part about standardization is the future.   Not only do DIN (and ANSI and ISO) standards insure that your 10mm socket truly is 10mm, there are multiple programs and research facilities who are constantly improving the current standards and innovating new ones.  Check out the DIN website for more information and as always shop KC Tool for all your DIN specific needs!

Penta-What? Pentalobe!

What is a pentalobe screw and why would you need a pentalobe screwdriver?  Let’s examine a brief history of this little beast.

Firstly, like a Pentagon (shape with five sides) a Pentalobe is a screw or screwdriver with five points.  They come in six sizes from 1 to 6.  The nomenclature of this can be confusing though, as different companies have different ways of naming their pentalobe sizes.  You will see TS1, which can easily be mistaken for Torx size.  You will also see variations on the letter P (P1, P2, Etc..) and PL (PL1, PL2…).  There even some who make it as clear as possible and call it Five Lobe.

Pents up close 2.jpgThe confusion doesn’t stop there, though.    In 2009 Apple launched the pentalobe screw, and that’s about all they did.  There was no regulatory sizing so the brains at iFixit reverse engineered the screw and made a driver to work with it.  Since it was similar in size to a Torx T2, the called it a P2.  After they did this, Apple released sizing information and revealed that iFixit’s P2 was actually a size 1.  It was after all this commotion that WIha released their set of pentalobes (to Apple Standards), so their PL1 is actually the same size as iFixit’s P2.  Did you get all that?  To keep things simple (and since this is the GERMAN tool blog) we will use Wiha’s sizing standard, PL1-PL6.

So now that we have sizes under our belt the ultimate question is why?  Why would someone need a five-pointed precision screwdriver?  The answer is simple.  Apple.  Not the fruit (though I suppose you could use a pentalobe screwdriver for digging out apple seeds).  Apple, the modern-day tech conglomerate which made Steve Jobs a household name.  Do you have a Mac Computer?  Or an iPad?  Or iPhone?  Do you want to get inside of that device and play around with the guts?  Then you are probably going to need a pentalobe precision screwdriver.

Which one you might ask?  Let’s take a look.

Do you have an iPhone 4, 4S, 5, 5C, 5S, 6, 6 Plus, 6S, 6S Plus, 6S, 6S Plus, SE, 7, 7 Plus?  You need a PL1 pentalobe.
Do you have an Apple Watch?  You will need a PL2 to change the band.
Do you have a MacBook Air or MacBook Pro with Retina Display?  PL4 is your guy.
To be specific, do you have a 15” 2009 MacBook Pro?  To get to the battery you will need a PL5.

Or if you are in doubt, Wiha has this nice 6-piece set that has all the sizes you need:

Pentalobes

What you really need is the PL3 and PL6 size drivers though.  What are they used for?  Nobody knows.  But won’t they look great on your bench?

Wiha Cameo in “Logan”

Logan-Wiha-2.5.gif

My wife and I saw the latest Wolverine movie last night, “Logan”. I have been a X-Men fan since I collected the comics as a kid. Imagine my surprise when the main bad guy, Donald Pierce (played by Boyd Holbrook), fixes his cybernetic arm with what appears to be a Wiha precision screwdriver! I won’t spoil anything for you other than this amazing cameo combining some of my favorite things: action, comics, and German hand tools! Check out the movie and see if you agree with me!

Hazet Announcement now at KC Tool

Hazet coming soon to KC Tool!

KC Tool is proud to present Hazet as our newest German hand tool manufacturer!

Many of you are probably already well aware of the Hazet German hand tool brand, especially if you are a Volkswagen or Porsche aficionado. Hazet’s association with these premier automakers have lasted decades.

Hazet was founded by Hermann Zerver in Remscheid, Germany in 1868. Ha-Zet came from a shorting of his first and last name. The company has continued to grow in the last 150 years but still maintains its family ties with the 4th and 5th generation (Hermann Jochen Zerver and Matthias J. Hoffmann, respectively) of Herman Zerver still running the company.

Hazet offers a full range of hand tools as well as a variety of specialty tools including automotive (like mentioned above), industrial, automation and aerospace. We are really excited to strengthen our existing industrial and automotive lines, with the addition of Hazet. It seems a natural fit in amongst our other outstanding brands. Some of the tools Hazet is most famous for are their tool trolleys: the “Assistent” series of tools (image below).

We will start carrying a full complement of Hazet tools starting the third week of March. Please keep your eye on our website. But if you need a reminder we will give you a heads up email to let you know when they are in stock!Screen Shot 2017-02-28 at 11.32.34 AM.jpg

Wiha 51 Piece Master Technician’s Precision Set

It is amazing what electronic devices people are repairing now that they used to just throw away and replace. Everything from mobile phones, to roku boxes, to playstations, to PCs. Electronics used to be disposable… now they are repairable. The rise of YouTube has been a boon to the education of the masses (your’s truly included).   The collective knowledge of people plus the internet is a powerful tool.  Want to see how to fix a broken iPhone screen, or change the lifters in your 2005 Dodge Caravan, or do a hard drive replacement on your mom’s 2012 iMac? Chances are someone has posted on Youtube a step by step video guide to walk you through almost any repair.
