Multi Purpose Drill Bits 2017-06-30T04:10:55+00:00

THE MOST VERSATILE DRILL BITS YOU CAN OWN!

Bad Dog Bits’ unique tip design creates a filing action to burrow through hard materials like tempered and high-speed steel and still drill soft materials like aluminum and PVC without ripping them apart. The Carbaloid tips resist fracture and stay sharper, longer than conventional bits. They’re SO DURABLE that they’re GUARANTEED FOR LIFE! Drill any combination of materials with the Bad Dog Multi-Purpose Drill Bits. Modify drilling speed to recommended drilling speed of the material in each layer.
Note: DO NOT USE AIR DRILL!

THESE DRILL BITS ARE GUARANTEED FOR LIFE!

How can we back Bad Dog Multi-Purpose Drill Bits like that? Because we make a quality bit that can take a bite out of pretty much anything. Take a look at the tip of a Bad Dog Multi-Purpose Drill Bit. They’re different than any other bit that you may have in your toolbox. This unique Carbaloid tip creates a filing action to burrow through hard materials like tempered and high-speed steel while still drilling soft materials like aluminum and PVC without ripping them apart, while resisting fracture and maintaining an edge longer than conventional bits. To get the best performance out of your new tool, please review the direction.

IT’S ALL IN THE TECHNIQUE

Because Bad Dog Multi-Purpose Drill Bits are different than other bits you may have used before, the drilling technique is also different. Spend a few minutes reviewing the following tips and tricks for a lifetime of happy drilling through most any material. If you run into any issues, please check out our troubleshooting section.

METAL (NOT Stainless)

  • Use a drill press
  • If you only have a hand drill, use heavy pressure and a cutting lubricant like Bad Dog Drool
  • DO NOT drill pilot hole

METAL (Stainless)

  • Use a “pulsing action” on the trigger to drill slow RPM when the material requires
  • Use a cutting lubricant to prevent blueing
  • DO NOT drill pilot hole

TILE

  • Know what kind of tile you’re drilling!
  • Porcelain and Glass tiles should be considered glass, very fragile and thus difficult to drill
  • Review the RPM guide for appropriate drill speeds

MARBLE/SLATE

  • Tape over drilling area to help prevent chipping and cracking of material
  • DO NOT use hammer drill
  • DO NOT drill pilot hole

GRANITE

  • Use hammer-action drill
  • Use cutting lubricant like Bad Dog Drool
  • DO NOT drill pilot hole

MASONRY

  • Use a regular hammer-action drill
  • Use hammer-action drill where rebar or other metal is present
  • DO NOT drill pilot hole

PLASTIC

  • Clean debris regularly from shank when drilling in order to prevent clogging
  • DO NOT drill pilot hole

WOOD

  • Best for rough drilling
  • For other projects, consider Bad Dog Rover Bits for your wood working

GLASS

  • Work on a flat surface
  • DO NOT let the body of the drill (not drill bit) slide into or hit the glass when the bit exits the hole
  • Use an oil based cutting lubricant
  • Mae a small reservoir from string or clay to hold the cutting lubricant in the drilling area
  • Drill pilot hole

MULTIPLE MATERIALS

  • Review the RPM Guide below
  • Adjust the drilling speed to conform to each material as it is being drilled

RPM GUIDE

The key to getting the best performance out of your Bad Dog Multi-Purpose Drill Bits.

DRILL BIT CARE

Sharp bits drill best

  • If the debris becomes dark while drilling, the bit is dull. STOP drilling!
  • Use the Diamond Wheel to sharpen the bit to 118° flat grind or repair/replace the bit under the Lifetime Guarantee
  • Run the pivot along the straight edge

Store properly in index to avoid chipping
Keep flutes clear of debris
Clean pitch from bits with oven cleaner
Coat with oil to prevent rust
Remove rust with steel wool

DO ANY OF YOUR DRILL BITS LOOK LIKE THIS?

Bad Dog Multi-Purpose Drill Bits are as tough as they come, but they are not indestructible. Look at the drill bits below to find out what went wrong, and how to prevent it from happening to you. The Multi-Purpose Drill Bits are covered by a LIFETIME SATISFACTION GUARANTEE. So even if any of this happens to your bits, we will replace them.

PROBLEM: UNNECESSARY PILOT HOLES
This is what happens when pilot holes are unnecessarily drilled.
SOLUTION
With Bad Dog Multi-Purpose Drill Bits, DO NOT drill pilot holes into stainless steel, metal, marble, or granite.

PROBLEM: DRILL BIT IS LOOSE IN CHUCK
This bit was not securely tightened into the chuck. If the bit is continually used, the bottom will completely burn off.
SOLUTION
Make sure the drill bit is snug and tight in the chuck.

PROBLEM: CHIPPED BIT/DRILLING TOO SLOWLY
The drill bit may become chipped when drilling too slowly.
SOLUTION
These drill bits are not like any you have used in the past. Take a look at the specialized drilling techniques and drill speeds for the materials you are working on.

PROBLEM: DRILLING TOO MANY RIVETS AT ONCE
Multiple rivets have fused to this drill bit
SOLUTION
After drilling out 2 or 3 rivets, remove the rivets from the drill bit. If they are not removed, they may become a permanent fixture.

PROBLEM: BENT DRILL BIT
While the shaft of the drill bit has some flexibility, if you try to flex beyond 15°, some permanent bending may occur.
SOLUTION
Because of the nature of the small bits, we recommend putting an even vertical pressure while drilling.

PROBLEM: MELTED BIT/DRILLING WITHOUT A TIP
The drill bit will melt if it is used to drill without a tip.
SOLUTION
If your bit has lost it’s tip, then it needs to be replaced. All Bad Dog Multi-Purpose Bits are guaranteed for life. For details on the lifetime warranty, please click HERE.

PROBLEM: INCORRECTLY SHARPENED DRILL BIT
This is an example of incorrectly sharpened drill bit.
SOLUTION
Sharpen the bit on a 118° angle. We recommend using our Diamond Wheel to assist with this, or you can send it back to us and we’ll sharpen it for you.

PROBLEM: DRILLING WITH A DULL BIT
When a dull bit is continually used, it can end up looking like this.
SOLUTION
Sharpen the bit on a 118° angle. We recommend using our Diamond Wheel to assist with this, or you can send it back to us and we’ll sharpen it for you.
