Hex Shank Auger Bits 6mm - 14mm Diameter

• For drilling fast, precise and clean holes in wood
• 'Lewis Pattern' auger bits featuring a precision machined threaded tip, cutting spur and 45° pre-cutter
• Sharp cutting spur and pre-cutter prevent splintering
• Threaded tip pulls the bit through the wood, reducing user effort
• Continuous, smooth-flowing flute ensures chip removal without jamming, even when drilling through wet wood
• Manufactured from high grade carbon steel with precision high-tech heat-treatment
• Cutting-end and 60% of the body length are hardened to HRC43-53, giving strength and durability
• Shank end and 40% of the body length are hardened to HRC25-35, allowing flexibility and ability to absorb stress, minimising the risk of 'breakage'
• 6mm diameter auger bits have a cylindrical shank and can be used in 10mm or 13mm capacity 3-jaw drill chucks
• 8mm diameter and above have hexagonal shanks, which lock tightly in a 13mm capacity 3-jaw drill chuck
