Sada vrtákov Michelin HSS na kov 13,0 mm priemer, dĺžka 135/205 mm, 5 ks

Set of 5 Michelin HSS drill bits for metal with a 13.0 mm cutting diameter, designed for workshop, construction, and maintenance drilling tasks. Each bit is manufactured from high-speed steel (HSS) to provide increased wear resistance and improved tolerance to heat during continuous or intermittent drilling. The set includes bits with a cutting length of 135 mm and a total length of 205 mm, offering extended reach for through-holes and deeper drilling operations in steel and other ferrous or non-ferrous metals.

Advantages

Michelin HSS drill bits combine durable high-speed steel construction with precise cutting geometry to deliver consistent hole quality and long life when used in appropriate materials. The 13.0 mm diameter provides a standard size for many mechanical and assembly needs, while the extended overall length allows access to recessed or deep workpieces. Heat resistance of HSS reduces wear when drilling at higher speeds, and the set format of five bits ensures quick replacement when a bit becomes worn or damaged.

Key specifications

How to use

Select the correct drill speed and appropriate cutting fluid for the metal being drilled to prolong tool life and improve chip evacuation. Secure the workpiece firmly and use suitable clamping to prevent movement. Pilot holes or step drilling can be used when drilling large diameters or hard materials. Position the drill perpendicular to the work surface, apply steady pressure, and withdraw occasionally to clear chips. After use, clean chips from the flutes and store the bits in a dry place to avoid corrosion.

Recommendations

For optimum performance when drilling steel, use moderate to high spindle speeds suitable for HSS, apply cutting lubricant to reduce heat buildup, and avoid excessive feed rates. Replace a bit at the first sign of significant wear or chipping to maintain hole quality and reduce risk of breakage.
