Gun Drill Bit — High Speed Steel — Length 65–89 mm (Woodworking DIY) Key benefits Precise deep-hole drilling: Gun drill geometry keeps the hole straight and consistent, ideal when accuracy matters in woodworking joinery and fittings. Durable cutting material: Made from High Speed Steel (HSS) for reliable edge retention and resistance to heat during prolonged drilling. Versatile length options: Available in lengths from 65 mm to 89 mm to match different hole depths and project needs. What it does and why you need it Designed to create clean, straight holes in wood for dowels, rods, and through-holes where alignment and depth control are important. Reduces rework by producing consistent results, making it useful for furniture assembly, cabinetry, and other DIY woodworking tasks. HSS construction provides a balance of toughness and cutting performance that suits repeated use in common woodworking environments. Important attributes Type: Gun drill bit — optimized for straight, deep-hole drilling. Material: High Speed Steel (HSS) — durable and heat-resistant for extended use. Length: Available from 65 mm to 89 mm — choose the appropriate length for the depth you need. Application: Intended for woodworking/D.I.Y. use. Practical use scenarios Dowel joinery: Drill accurate, straight holes for dowels when building chairs, tables, or cabinets. Cable or rod routing: Create long through-holes for running cables or wooden rods through assembled panels or frames. Long, aligned fastenings: Prepare straight alignment holes when assembling multi-piece fixtures that require precise hole placement. Usage notes Select the bit length that matches the required hole depth to avoid excessive overhang. Secure the workpiece and use appropriate drilling speed and feed to maintain a clean cut and minimize tear-out. Inspect and replace the bit if edges become worn to preserve hole quality. This HSS gun drill bit is a practical tool for DIY woodworking projects that require straight, reliable holes in wood components.
