Forstner Drill Bits: Not Your Ordinary Drill Bits

We all know that drill bits are one of the useful tools used by construction workers or DIY workers at home. But this drill bit that we will be talking about is a unique one and if you are curious about the origin of things, I am too. So sit back and enjoy as we go back to the history about Forstner drill bits. 

I did my research about this drill bit in wikipedia and woodworkinghistory.com but came up with a tidbit information about Forstner drill bit. Seems there was this gunsmith and his name is B enjamin Forstner.

If you have any idea about guns, you will know that during the early years of gun manufacturing, grips and gun stocks were designed by hand to each gun. And this required great skills in drilling the recesses necessary to accommodate the barrel and stock of the gun.

To quote Wikipedia:

The Forstner bit was "patented on September 22, 1874, [and] was to make him a rich man. Without the lead screw (which Forstner called the "gimlet-point") and cutting lips of more conventional wood boring bits it would prove especially useful to gunsmiths like himself and other high-end woodworkers. The bit was unsurpassed in drilling an exceedingly smooth-sided hole with a flat bottom. It was better than the Russell Jennings twist bits for boring at an angle and not following the grain of the wood.

Forstner drill bitsare unique type of drill bits because of its ability to drill overlapping holes, notches on the edges of a workpiece and angled holes on the face of the material. For example, pocket holes. The drill bit will cut whether or not the center spur hits the material. This is what makes Forstner drill bit unique.

As time pass by, patents has expired and a lot of manufacturers urged to improve the design. One of those companies is Colt from Germany. They manufacture a unique Forstner-style bit in France.

Unlike the traditional Forstner drill bit, the Colt bits have a unique design and geometry that creates a clean, flat-bottom hole without burning and clogging. And the first thing that you will notice is the entire circumference of the bit is not a cutting edge as it is on cheaply made bits. The colt bits have sort of a scoring tooth that quickly scores the outside diameter of the hole which prevents burning. There is also difference in the flat cutting edges on the inside that actually do the bulk of the cutting.  Another  advantage of this unique cutting edge geometry is that it facilitates sharpening the bit when required. And because there's less tendency of overheating the bit won't easily get dull.

Carbide. This is another improvement of the Fostner drill bitsin over the years of introducing carbide for the cutting tools. The tough carbide edges will last many times longer than conventional steel bits.
