Wood Drill Bit DeWalt DT4518 18 x 200 mm for Wood Drilling

DeWalt DT4518 18 x 200 mm wood drill bit is designed for drilling clean, accurate holes in solid timber and common wood-based materials. With an 18 mm diameter and 200 mm overall length, the bit accommodates through-holes and deeper drilling tasks typical for carpentry, joinery and general construction. The drill bit is intended for use with hand-held and stationary drills that accept standard straight shanks and is suitable for both professional tradespeople and DIY users engaged in woodworking projects.

Advantages

The DeWalt DT4518 offers precise hole geometry to reduce splitting and produce smooth bore edges. Its length provides reach for drilling through thick boards or creating long through-holes while maintaining bit stability. The bit is made to deliver consistent performance in timber and engineered wood products, reducing chatter and improving centring for repeatable results.

Suitable for

• Through-holes in solid timber and laminated boards
• Deep drilling for joists, beams and structural timber
• Joinery and carpentry installations (hinges, dowels, fastenings)
• General woodworking and renovation tasks

Key specifications

• Diameter: 18 mm
• Overall length: 200 mm
• Material suitability: solid wood and common wood-based panels
• Shank type: standard straight shank (suitable for chucked drills)
• Typical applications: through-holes and deep bore drilling

How to use

Secure the DeWalt DT4518 firmly in a compatible drill chuck and set the drill to an appropriate speed for the wood being worked. Mark and, if necessary, pilot the hole location before drilling to maintain accuracy. Apply steady, even pressure while drilling; allow the bit to cut without forcing to avoid overheating or splintering. For deep holes, periodically withdraw the bit to clear chips and reduce friction. After use, clean wood debris from the flutes and store the bit in a dry place.

Usage recommendations

Use lower to medium drill speeds for hard or dense timbers and medium to higher speeds for softwoods. When drilling plywood or veneered panels, support the workpiece to minimise splintering at the exit. Wear appropriate eye and dust protection and follow the drill manufacturer's safety guidance.
