Projobber 2.5mm x 57mm 135° Split Point Cobalt Steel Drill 096-53-CM0250 Front Cover


  • Material composition: Made of a combination of high-speed steel (HSS) and cobalt alloy to enhance the drill bits' hardness, heat resistance, and overall strength
  • Hardness: Cobalt steel drill bits are extremely hard, typically with a Rockwell hardness rating of 66-68 HRC which make cutting through tough materials without dulling quickly possible
  • Heat resistance: Significantly improves the drill bit’s heat resistance compared to regular HSS drill bits and reduces the risk of overheating and prolonging their lifespan
  • Abrasion resistance: Excellent abrasion resistance and can maintain the drill bit’s cutting edges for a longer time, even when drilling through hard materials like stainless steel or cast iron
  • Precision and accuracy: Designed to provide precise and accurate drilling; perfect for applications where accuracy is crucial, such as metalworking and machining
  • Versatility: Suitable for drilling through a wide range of materials, including metals, alloys, stainless steel, cast iron, and harder materials like titanium or hardened steel

Projobber 135° split point Cobalt steel drill bit improved centering, reduced drilling pressure, faster cutting, and improves chip evacuation compare to 118° split point HSS drill bit.

Drill Bit Dimensions:

  • Diameter: 2.5mm
  • Flute length: 30mm
  • Overall length: 57mm
