HARFINGTON Twist Drill Bit 1/2" Dia High-Speed Steel 6542 Reduced Shank 6" Overall Length with Gold Polished Surface for Drilling Hard Metals, Stainless Steel, Alloy Steel

Material: Made of high-speed steel 6542, with higher hardness and good wear resistance, impact resistance and heat hardening, and is suitable for cutting workpieces with larger size and heavier load.Polished Surface: The gold polished surface treatment enhances the twist drill's improved corrosion resistance, reducing friction during drilling operations and promoting smoother chip evacuation, minimizing heat generation, and enhancing overall drilling efficiency. Features: Can take into account a variety of models, hand drill, percussion drill, lithium drill, and bench drill can be adapted, effectively for precision drilling tasks on various workpieces. Applications: Jobber drill is used for drilling through hard materials such as stainless steel, alloy steel, cast iron, aluminum, copper, wood, malleable iron, aluminum, plastic, and other metals commonly encountered in machining applications. Note: Use proper speed, pressure, and heat control when using these drill bits to maintain efficiency. In the drilling process, the appropriate use of cutting fluid or oil for cooling and lubrication, to extend the service life of the drill.

• Size - Working Diameter: 1/2-inch; Working Length: 115mm / 4.53-inch; Reduced Shank Diameter: 3/8-inch; Total Length: 150mm / 5.91-inch
• Long Lasting Material: Made of high-speed steel 6542, improved corrosion resistance, the gold polished surface treatment enhances the twist drill's improved corrosion resistance, reducing friction during drilling operations and promoting smoother chip evacuation, minimizing heat generation, and enhancing overall drilling efficiency.
• Fast Drilling - The fully ground spiral groove design of the metal drill bits can quickly remove debris, reduce friction and heat, and drill faster. The 135 ° straight shank split point reduces walking on the working face, making drilling accurate and easy.
• Application - Twist drill is suitable for hardened materials and hard metals, such as stainless steel, mould steel, alloy steel, cast iron, aluminum alloy, copper and hard plastics, and also suitable for soft materials like wood.
• Note - Please note that these small drill bits are not suitable for glass, tile, wall, stone or ceramic materials, pay attention to speed, pressure, and heat control when drilling. Appropriate use of cutting fluid or oil for cooling and lubrication can extend the service life of the drill.
