Bad Dog Multipurpose Bits Are The Most Versatile 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 the recommended drilling speed of the material in each layer. Note: DO NOT USE AN AIR DRILL!

THESE BITS DRILL THROUGH JUST ABOUT ANYTHING-
MASTER 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.

RPM GUIDE

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 a hammer drill
DO NOT drill pilot holes

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 woodworking

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

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.

To get the best performance out of your new tool, please make sure you are using bits correctly.

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
