IRWIN HSS Cobalt Drill Bit, 7.0mm, 109mm
High-performance IRWIN 7mm cobalt HSS drill bit for stainless steel with 135° split point and heat-resistant design.
The IRWIN HSS Cobalt Drill Bit is engineered for precision drilling in stainless steel and other high-alloy materials. Its 135° split point grinding ensures excellent self-centring capability and reduces drilling pressure, making it easier to start holes accurately. The industrial-quality ground flute design allows for high-accuracy drilling and efficient chip removal, enhancing productivity in demanding applications.
Constructed from high-speed steel (HSS) with 5% cobalt content, this drill bit boasts superior red hardness (heat resistance), resulting in a significantly extended tool life compared to standard HSS bits. The golden tempered surface finish not only provides an attractive appearance but also indicates improved durability and performance.
