Easy to replace sharpening strips keeps
the DrillGadget priced right even more
so. Simply slit your own from a sheet of

store or home center.
Sharpen not only your
118 degree drill bits, but
your 135 degree split tip
drill bits as well, both up to
1/2 in. diameter. More
135 degree split tip drill bits as well are
just as easy to sharpen with this drill bit
sharpener. Even this hard titanium coated
split tip drill bit, with even more
complicated geometry is easy to do. More

Sharpen your drill bits when you need and
without aggravation. It's amazing the new life
sharp drill bits will bring to both a cordless
drill and a drill press.
The DrillGadget, the easy to use and handy drill bit sharpener,
positions your drill bit perfectly allowing you to dress the cutting
edges at the precise compound angle the manufacturer intended.
Polycarbonate is a high impact resin used for robust products.
Because it is so tough is the reason it costs twice as much as
typical plastics. This robust manual drill bit sharpener is
molded with Polycarbonate.
Aluminum Oxide and Silicon Carbide are established metal
removing abrasives. One sheet you can buy anywhere literally
will last for thousands of dressings.

Inventor's Story

Several years ago while playing in my workshop
with my new drill bit sharpener, a neat grinder
that two million others and your's truly each
paid $100 or so for, I was very impressed with
the results I got bringing old drill bits back to
life. Not a bad gift idea I thought but a little
pricey. After an hour or so sharpening drill bits
and becoming less excited about my new tool, I
put it aside and retired to my favorite chair.
Being the frugal person I am, I sat in thought  
why I paid $100 for a tool to put new points on a
set of drill bits I could replace for $20. I went to
bed telling myself I would have it for a long time
and wouldn't have to buy any more drill bits,
unless of course I got too carried away grinding
them and they became too short to use.

I wasn't too far into my walk along the canal the
next day while thinking about sharpening drill
bits and how to simplify the task because I
convinced myself that if two million people paid
$100 for a drill bit grinder to make sharpening
drill bits easier, a billion people, maybe less I
agree, might pay $5 to $10 for a priced right
tool that will also make their drill bits as sharp
as they ever have to  be. I didn't know what the
concept was, but I knew what a drill tip was all
about and decided geometry, and not bells and
whistles, was going to be the name of the game.
 It was going to have to preserve the critical
geometry of a drill tip, both 118 degree and 135
degree including split tip, be easy to use, small
enough to keep with the bits, and manual, not
only because a motor wouldn't fit the budget,
but because of the need to always have it
available for the worksite as well as in the
workshop for home projects. It had to be a
useful hand tool, as useful as a chisel or a
screwdriver. And also very important, I wanted
an everyday sharpening media, easily
renewable, like an existing aluminum oxide or
silicon carbide product  from a sanding belt
manufacturer. Diamond impregnated sheets
came to mind as well.

It took a half dozen prototypes or so to get
where I wanted my drill bit sharpener to be. A
handful of quality parts all relating to drill tip
geometry, and the realization that strips of
everyday aluminum oxide or silicon carbide
sandpaper worked very nicely with bits almost
up to carbide is what came to life as a true
everyday gadget, something that easily  erases
the complicated task of sharpening drill bits.

The DrillGadget is not a drill bit grinder and isn't
intended to be. It's a precision cutting edge and
chisel point restorer, and because of that, it is a
accurate drill bit sharpener.  It is robust and  
molded from space age resins,  process
controlled to provide precision gripping and
positioning of a wide range of bit sizes, and
several types as well, and allows the user to
determine what grit abrasive should be used
when sharpening  drill bits, and honing them as
well as how much sharpening is needed.

The complexity of drill tips surprises many
people. They are not simple points like a pencil.
 Along with the precise geometry, different tip
angles are being marketed and as everyone
knows, a huge range of drill tip diameters. Drill
bit sharpeners have to be accurate and
versatile, and the DrillGadget definitely is. Drill
tips are complicated, but sharpening them with
a DrillGadget isn't.

Drill bits are made from a wide range of
materials. Every day drills are made from tool
steels followed by a  range of harder materials,
right up to titanium coated and carbide. Drill bit
sharpeners are expected by consumers to
handle not only the softer materials, but the
harder materials as well. The Drill Gadget,
although not a drill bit grinder, holds it's own as
a drill bit sharpener.

I didn't intend to come up with another drill bit
grinder. Why invent another "better mousetrap"?
I wanted something simple and small that could
be used at the spare of the moment. If you don't
intend to use it on a drill bit you tried to ram
through concrete, you'll find the DrillGadget is
everything I intended. And unless you run over
it with a truck, it will last many years and as you
already know, your supply of sharpening media
will as well.

Take care and work carefully,
