MAKITA D-17712 TCT Masonry Drill Bit Straight Shank 20x400 mm

MAKITA D-17712 TCT Masonry Drill Bit Straight Shank 20×400 mm
Features The MAKITA D-17712 is a high-quality metric masonry drill bit notable for its large size and extra length. The drill bit tip is made of tungsten carbide (TCT), a robust material that resists wear and high heat while drilling concrete.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 400 mm (or 40 cm) makes it ideal for applications requiring drilling through extra-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).
