Spade bit

The right spade bit starts with the target hole size and the material you’re drilling. For wood, pick a diameter that matches the hole you need and a shank type that fits your drill’s chuck. Look for hex shanks (1/4 in) for quick-change chucks to avoid slipping, and consider length to reach deeper holes. You’ll find options like an 18 mm wood flat drill with a universal hex shank for versatile use, and a 26 mm x 152 mm self-cut speed bit designed for fast, clean wood holes. Choose carbon steel with durable coating for longevity.

A universal hex shank means the bit fits most drills equipped with 1/4 inch quick-change chucks. This matters because it prevents slipping under torque and allows faster bit changes during work, saving time on multi-step projects. In this range, some bits advertise the universal hex shank, ensuring compatibility with a wide array of drill tools in common markets. If you frequently switch between drills or tools, a hex-shank option helps you maintain steady performance without extra adapters.

Homeowners typically choose spade bits for cabinetry, shelves, and general woodworking where quick, rough holes are acceptable. Professionals may opt for specific sizes like 18 mm or 26 mm with longer reach (152 mm) for deeper drilling or cleaner entry in carpentry tasks. In this assortment, you’ll see wood-oriented bits with features like self-cut tips and polished heads, which reduce effort and improve hole accuracy on various wood types, from softwood to hardwood.

Keep spade bits clean and dry after use to prevent resin buildup and corrosion. Wipe away wood dust and debris, and lightly oil the hex shank to prevent rust. Store bits in a dry, organized container so the shanks don’t get bent or nicked. Periodically inspect the cutting edges for dullness or chipping, and replace any bit that shows significant wear. Proper storage and minimal exposure to moisture will preserve performance and prolong tool life.

Common choices include 18 mm and 26 mm diameters, with lengths around 152 mm for reach in deeper work. Some options feature a universal hex shank for broad compatibility with quick-change chucks, while others emphasize fast-cut design like self-cut tips for quicker hole progression. Material quality varies, with carbon steel and heat-treated coatings highlighted for durability. These options let you tailor the bit to your wood type and your drill’s chuck system without sacrificing performance.

Pair spade bits with complementary bits for multi-material projects. Use HSS bits for metal, or high-performance SDS+ bits for masonry tasks, depending on the job at hand. For wood projects, you can rely on spade bits for holes and switch to a smaller pilot bit if needed to reduce wandering. In this collection you’ll see related wood drilling options and separate masonry or metal bits, so plan your set based on the materials you expect to encounter and the drills you own.
