Features:

• Thunderweb design is characterised by a conical shaped web which gets thicker towards the back of the drill bit. Standard drill bits have a constant thickness throughout their length. Even at the narrowest point the Thunderweb core is thicker than that of a standard drill bit
• Parabolic web cross section: Large web thickness. Strength built in
• Flute geometry - Thunderweb flute form ejects hot chips rapidly. Dissipates heat better increasing life time
• 135° Split point - Precision starting, drill bit won't walk on material surface
• Polished finish reduces friction and extends drill bit life
• Impact resistant ABS case with added rubber corner protection
• Accepts higher feed pressure and torque equalling less breakages

Includes:

• Round shank drill bits ø: 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10mm
