Extra-Long Drill Bit Set | HSS High-Speed Steel | 300mm Length for Deep Drilling in Wood & Steel

Tackle deep drilling tasks with this 300mm extra long drill bit, engineered from HSS High Speed Steel for demanding applications. Its extended 12-inch length provides exceptional reach for boring through thick materials, joists, or tight spaces where standard bits fall short. Available in diameters from 7mm to 16mm, it delivers precise, clean holes in steel, wood, and other tough substrates. Features and Benefits - 300mm Extra Long HSS Construction - Provides superior reach for deep hole boring through thick beams, layered materials, and confined spaces where access is limited. - High Speed Steel (HSS) Material - Offers excellent heat resistance and durability, maintaining a sharp cutting edge longer than standard carbon steel bits for consistent performance. - Double Groove (135° Split Point) Design - Ensures faster cutting starts with reduced walking or skidding on curved surfaces, increasing accuracy and user control. - Round Shank Compatibility - Fits securely into all standard 3-jaw chucks from hand drills to drill presses, providing a firm grip and minimizing slippage during operation. - Precision Ground Flutes - Efficiently channel debris out of deep holes, preventing clogging and reducing heat buildup for smoother, safer drilling. Applications - Plumbing and Electrical Installations - Drill through wall studs, floor joists, and ceiling beams to run pipes, conduit, or cables in new construction or renovations. - Metal Fabrication and Repair - Create deep, clean holes in steel plates, angle iron, or tubing for bolts, mounts, or assembly in workshop or jobsite settings. - Woodworking and Carpentry - Bore through stacked lumber, thick timbers, or furniture components for dowel joints, hardware installation, or ventilation passages. - General DIY and Maintenance - The ideal solution for any project requiring a deep, straight hole where a standard-length drill bit cannot reach the required depth.
