XMSSAA Tap Drill Hex for Stainless Drill Chamfer Spiral Cobalt Nitride for Iron and Metalwork Set, 6-Piece Set, Shank, Steel, Tap, Tap, Drilling,

[For Stainless Steel]: The spiral shape is ideal for stainless steel, allowing for smooth drilling with minimal welding. It's also suitable for threading in hard materials like stainless steel, steel, and aluminum, as well as soft materials like wood, vinyl, and resin. It's the perfect tool for DIY, home improvement, and engineering projects, including drilling, tapping, and chamfering. [Industrial Cobalt High-Speed Steel] This tap drill is made of HSS-Co M35 steel and features an AlTiN titanium nitride coating, which increases the aluminum content and strengthens the surface, achieving a hardness of HRC89. It offers superior heat resistance compared to standard drill taps and reduces heat generated during friction. It improves the drill's high-temperature resistance and abrasion resistance, making it ideal for high-speed drilling. [Spiral Tap Drill] This chamfering tap features a spiral design and is compatible with machines with forward and reverse rotation, allowing for easy chip removal and simultaneous drilling and threading. Compared to standard straight tap drills, this tap has the advantage of reducing the risk of cutting edge breakage and fracture, resulting in a longer service life. [Easy to Use] This tool combines three functions: threading, drilling pilot holes, and chamfering. It significantly reduces the time and effort required for drilling pilot holes, making work easier. Its universal hexagonal shaft also makes it compatible with impact drivers, electric drills, and cordless drills. [Product Specifications] Set includes six screws: M3x0.5, M4x0.7, M5x0.8, M6x1, M8x1.25, and M10x1.5. Material: HSS-Co M35. Surface treatment: Titanium nitride aluminum coating. Shaft diameter: 1/4" hex shank (6.35mm). Various sizes are available to accommodate various models. A storage case is included to prevent wear during transport and make it easy to carry.
