Everything You Need to Know about Spade Bits
                     EVERYTHING YOU NEED TO 
KNOW ABOUT SPADE BITS
Spade Drill Bits are also referred to as 
paddle bits and are excellent flat blades. 
They're commonly employed by tradesmen 
like electricians and plumbers for drilling 
holes in studs in walls for running wiring or 
pipes. Still, they even have an area within 
the woodshop for drilling on fair 
woodworking projects.
WHAT IS A SPADE BIT?
The spade bit is a flat, broad blade 
of a bit that features a pilot point 
attached to a 1/4-inch diameter 
shank, which is chucked into both 
regularly-chucked drills and quick-
chuck impact drivers. Each fringe of 
the spade bit's flattened portion is 
sharpened, and therefore the 
bottom corners of the sharpened 
area have a pointed tip, counting on 
the design and brand of the bit. 
TIPS FOR USING A SPADE BIT
There are various methods for drilling 
clean holes with a spade bit, such as: 
• Tightly attaching a sacrificial board 
to the backside of the workpiece 
when drilling, OR
• Drilling partway through the 
workpiece until the pilot point 
penetrates through the wood, then 
reversing the board and completing 
the opening by drilling from the 
backside.
HOW TO USE THE SPADE BIT?
• Mark the middle point of the 
opening to be drilled on the wood, 
and chuck the shank of the bit into 
the drill.
• Align the purpose of the pilot tip of 
the bit with the mark on the wood 
and adjust the hand-held drill's 
angle so that the shank of the 
Spade drill bit for metal is square 
and perpendicular to the surface of 
the wood.
