Concrete drill set - widia sds plus 4-blade (5 pcs) / teger

Set of concrete drill bits - widia SDS PLUS 4-blade (5 PCS) by TEGER / made according to DIN 8035, intended for drilling holes in high-density materials. A modern, progressive spiral design and 4 edged blades made of high-quality sintered carbide ensure high work efficiency and guarantee a precise hole of the desired diameter. The geometry of the widia guarantees perfectly smooth holes, and the specially designed spiral reduces vibration and ensures low wear and distortion of the drill diameter. Durable 4-edge tip made of YG8 sintered carbide, preventing the drill from jamming in the reinforcement. Made of special steel with AISI (American Iron Steel Institute) specification - 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 positive effect on the elasticity, hardness and strength of steel. Drill diameters included: 5x110/6x110/6x160/8x160/10x160 mm.
