Drill bit set DeWalt DT4797 — 4-piece flat (spade) bits

DeWalt DT4797 is a 4-piece set of flat (spade) drill bits designed for creating larger diameter holes in wood and wood-like materials. Each bit in the set features a standard round shank compatible with most hand drills and drill drivers. The set is intended to provide rapid material removal and straightforward holemaking for carpentry, installation and general woodworking tasks where clear, wide bores are required.

Advantages

The DeWalt flat bits offer fast cutting performance and efficient chip ejection thanks to their wide paddle profile and central pilot point. Standard shanks ensure compatibility with common chucks and allow quick bit changes. The set format supplies a small range of commonly used diameters in one convenient kit for on-site or workshop use. The simple geometry reduces clogging and helps maintain steady drilling speed in soft and composite woods.

Suitable for

• Drilling larger holes for cables and pipes in timber and worktops
• Carpentry tasks such as making holes for hinges, bolts, and fasteners
• General woodworking where fast material removal is needed
• Installation and repair work requiring straightforward round bores

Key specifications

• Bit type: flat (spade) drill bits
• Set quantity: 4 pieces
• Shank style: standard round shank for drill chucks
• Material compatibility: wood and wood-like materials
• Application: manual and powered drilling with hand drills and drill drivers

How to use

Select the required diameter from the set and insert the round shank into a compatible drill chuck, tightening securely. Position the pilot point on the marked drilling spot, apply steady axial pressure and run the drill at an appropriate speed for the wood species. Withdraw the bit periodically to clear chips if necessary, and complete the hole until the desired depth is reached. Maintain firm control of the drill and follow standard safety measures such as clamping the workpiece and wearing eye protection.

Usage recommendations

Use moderate drill speeds for hardwoods and higher speeds for softer woods to balance cutting efficiency and heat generation. Keep the bits clean of resin buildup and sharpen or replace worn paddles to preserve cutting performance. For through-holes, support the exit side to reduce splintering.
