Zestaw wierteł do betonu - widia SDS PLUS 4-ostrzowe (5 SZT.) / TEGER

Set of concrete drills - SDS PLUS 4-blade carbide bits (5 PCS.) by TEGER / made according to DIN 8035 standard, designed for drilling in high density materials. Modern progressive spiral design and 4 edge blades made of high quality sintered carbide ensure high work efficiency and guarantee obtaining a precise hole of the desired diameter. The geometry of the carbide bit guarantees perfectly smooth holes and the specially designed spiral limits vibrations and ensures low wear and distortion of the drill diameter. Durable 4-blade tip made of sintered carbide YG8, preventing the drill from jamming in the reinforcement. Made of special steel with AISI specification (American Iron Steel Institute) - A322 / G5140 resistant to bending, abrasion and torsion. Alloy content: Manganese - increases impact strength and hardness Chromium - provides greater resistance to abrasion, silicon - has a beneficial effect on the elasticity, hardness and strength of steel. Drill diameters in the set: 5x110/6x110/6x160/8x160/10x160 mm.
