Cutting edge strength oriented design. Suitable for sticky materials such as stainless steel and low carbon steel. Good balance of sharp cutting and cutting edge strength Middle to high feed rates of steel drilling, GM Chipbreaker alternative. Sharp cutting, prevents chattering. For low to medium feed rates of steel. e id si e g d e O Wide chipbreaker Chipbreaker Cross-section Chips from Outer edge % e id si e g d e Chipbreaker Cross-section Flat chipbreaker Chips from Inner edge Workpiece Material S50C S50C SUS304 Indication of tool life of MagicDrill How to judge tool life Indication of judging tool life Judgement of tool condition and insert wear When an insert is new the toolholder is slightly bent to the side during drilling. (therefore, the drill diameter is slightly bigger during drilling). Once drilling is finished, the toolholder will return back to normal size. No tool marks will appear on the finished surface (although this depends on workpiece and cutting condition: during external drilling slight tool mark might appear.) When an insert is at the end of its tool life, Gradually the external corner part gets worn out, the toolholder does not bend slightly outwards, it starts to bend inwards. After the drilling is finished, the toolholder returns to the normal position. When taking off a toolholder under this condition the cutting edge of the insert creates external tool marks on the finished surface of the workpiece. Checking hole diameter When hole diameter is measured, suddenly it shows small diameter. In this case, a worn out insert can be the cause. Checking the surface on the outlet side If insert wear progresses, the burrs of penetrated hole entrance becomes bigger. This is a clear indication that the tool must be exchanged. Variation of drilling noise Light drilling noise at the beginning turns to brady noise which contains vibration noise. Variation of vibration As the end of tool life is getting closer, there is more vibration and the drilling noise changes. However, when drilling smaller diameters these factors are difficult to detect. K39 Drilling
