4932343276 - HSS trephine bit, 20 x 30 mm

• 100% Faster - Speed and time savings are achieved due to the following factors.
- Firstly the annular cutter principle of only cutting material from the periphery of the hole as opposed to the twist drill which must cut the complete diameter of the hole.
- Secondly the benefit of two aggressive sharp angles per cutting edge help to achieve faster feed rates and lower cutting resistance.
• 30% More productivity - Because the annular cutter is only cutting material from the periphery of the hole.
• Less motor energy and driving power is required. The larger the drill diameter the greater the energy saving.
• Longer lifetime - The annular cutters cutting edges do less work than the twist drill resulting in more holes between sharpening.
• Thick 6 mm body together with special tooth geo-metry ensures high stability and reduces to a minimum the risk of breakage due to overloading.
• Thick walled HSS annular cutters for increased durability and life time.
• With standard 19 mm Weldon reception.
• 30 mm depth of cut.
