Highly Efficient Drilling - The SDS plus-5X Drill Bit offers highly efficient drilling in reinforced concrete. The geometrical form of the 4-cutter head prevents jamming and breakage for optimal resul more→ts. The “turn-angle” head and the large and short dust removal channels within the 4-flute design provide fast dust removal so the bit can slice through concrete and rebar quickly with reduced wear. For efficient work and exact hole diameters, the centring tip guides drilling from the start, to prevent wandering, which can falsify the hole diameter. The bit is intended for use on masonry, concrete and reinforced concrete. It is compatible with rotary hammers with SDS plus holders. As proof of qual…

The Irwin Metric HSS Cobalt Drill Bits are perfect for drilling stainless steel and other high alloys. Their 135 split point grinding ensures perfect centring and reduced drilling pressure. An industr more→ial quality ground flute ensures high accuracy drilling and fast removal of chips. The drill bit body is manufactured from high quality HSS steel containing 5% Cobalt (Co). The added 5% Cobalt improves the red hardness (heat resistance) of the drill bit and results in significantly extended life. It has an attractive golden tempered surface finish. Diameter: 6.0mm.Working Length: 57mm.Overall Length: 93mm.

The Osborn HSS Co8 M42 Long Series Cobalt Drill Bit is great for drilling deep holes in stainless steels and difficult to cut materials such as titanium and inconel. Specifications • Diameter: 8m more→m • Working Length: 109mm • Total Length: 165mm
