1-1/8-Inch Spade Bit Set

The Bosch DSB1015 set contains twelve black-oxide spade bits, each 6.0 inches long with a 1-1/8-inch cutting diameter. A 0.25-inch threaded hex shank fits standard drill chucks and reduces slippage during use. The bits are designed for fast, clean holes in wood and similar materials.

Upgrade from Standard Flat Bits

The full-cone threaded tip pulls the bit through the workpiece with less pressure than a plain spade bit. Contoured paddles and spur-and-reamer tips clear chips quickly and reduce breakout on the exit side. The improvement is worth it when hole quality and drilling speed matter more than basic cost.

Hex Shank Compatibility

The 0.25-inch hex shank locks into any three-jaw chuck or quick-change adapter without a separate collet. Black-oxide finish resists corrosion and extends service life in damp conditions. The 12-piece pack covers repeated jobs without needing individual replacements. Not suited for metal, masonry or holes larger than 1-1/8 inches.

Questions about this item

What chuck size does the 0.25-inch hex shank on these 1-1/8-inch spade bits require?

The hex shank power groove fits a standard 0.25-inch chuck, reducing slippage during high-torque drilling in wood.

How should the full-cone threaded tip be engaged to avoid the common mistake of forcing the bit?

Let the self-feeding threaded tip pull the bit through the workpiece; apply steady pressure without forcing to prevent binding or breakout.

When will the spur and reamer tips on these 6-inch bits need replacement?

Replace bits when the spur or reamer edges dull enough to cause tear-out or when the threaded tip no longer self-feeds cleanly.
