MAKITA D-17740 TCT Masonry Drill Bit Straight Shank 20x600 mm

MAKITA D-17740 TCT Masonry Drill Bit Straight Shank 20×600 mm
Specifications With a size of 20 mm (nearly 3/4 inch), this drill bit is a large size used for large pipe conduit holes or very large anchor/fixing bolt holes. Its length of 600 mm (or 60 cm) makes it ideal for applications requiring drilling through very thick structures. The drill bit features a round/straight shank, requiring an adequately large drill chuck (typically a high-power power drill capable of clamping a 20 mm bit).
