Six-piece wood spade bit set

This DelitonGude set contains six spade drill bits ranging from 3/8 inch to 1 inch. The bits are made from carbon steel and feature a 1/4 inch hex shank that fits quick-change impact drivers and drill drivers. They are designed for boring flat-bottomed holes in wood, fiberglass, plastic and PVC. The deep-flute paddle design helps clear chips quickly during use.

Practical limits of the hex shank interface

The 1/4 inch hex shank reduces slippage in quick-change chucks and supports a maximum operating speed of 3500 RPM. The geometry is optimised for softer materials such as wood and plastic; it is not suited for metal, masonry or other hard substrates. Chip removal remains effective within the stated speed range, but performance drops if the bits are forced beyond the recommended materials.

Upgrade from standard twist bits for large holes

These spade bits replace smaller twist drills when you need clean, flat-bottomed holes up to 1 inch in diameter. The double-side cutting spurs cut faster and leave a smoother finish than a conventional bit in the same sizes. The jump is worth it for repetitive woodworking, electrical rough-in or plumbing tasks where hole quality and speed matter more than precision piloting.

Questions about this item

Which set of spade bits covers the sizes I need for common woodworking tasks?

This six-piece set provides 3/8", 1/2", 5/8", 3/4", 7/8" and 1" bits, covering the standard range for flat-bottomed holes in wood, fiberglass, plastic and PVC.

What does the 3500 RPM rating mean when I am drilling with a cordless drill driver?

The bits are rated for a maximum of 3500 RPM, so they will handle the high speeds of modern impact drivers without overheating or losing their cutting edges.

Will the 1/4" hex shank work with my quick-change impact driver and prevent slipping?

Yes, the 1/4" hex shank is designed for quick-change chucks on impact drills and drivers, giving a positive lock that stops the bit from spinning in the chuck under load.
