Newlec Drill Bit High Speed Steel 9.5mm

When cleanliness of breakout is critical, turn off hammer action and use ‘rotary only’ mode for the last part of the drilling process.Recommended speed for these cores is largely governed by the power tool itself. This is because they are designed to be used in power tools where in the majority of cases there is no facility to regulate the speed (SDS Plus, SDS Max machines etc.).If used in a machine where speed regulation is possible, a general recommendation is the larger diameter of the core drill being used, the slower the speed. · · · Precision machined arbor flats allow users to easily use grips or a spanner to lock on to the arbor for easy separation of core assembly · · Machined Tommy Bar hole allows users to locate a Tommy Bar for hassle free disconnection of arbor and core drills · · 2.5mm ultra thin wall means there is dramatically reduced drag resulting in extreme drilling speeds · · Ultra hard tungsten carbide tips provide increased wear resistance allowing users to operate the core on ‘hammer action’ for rapid drilling speeds · · Easy to start: The 135 degree split point makes it easy to start the drill bit in the material. · · Rust and corrosion resistant: The black oxide finish helps to protect the drill bit from rust and corrosion. · · Versatile: The 9.5mm diameter makes this drill bit a versatile option for a variety of applications. · · Straight shank: The straight shank makes it easy to use the drill bit in a power drill.
