When you go to buy a drill bit, what do you need? Just a drill? or do you actually want a HOLE?

Rigorous testing has proven that the Gold Series Drills outperform most other drills on the Australian market by more than 30% - giving you more holes for your dollar in every single drill bit!

DRILL FEATURES

• M2 HSS Fully ground M2 HSS material increases drill life
• Titanium Nitride coating reduces heat and increases lubricity for extended life
• 135 Degree Split Point cuts faster and reduces wandering
• Alpha gold series drills are packaged is a reuseable plastic hang pack to keep your drills safe, clean and dry

DRILLING PRACTICE

The flute form, web thickness and split point of the standard Alpha drills are suitable for most materials forming fine chips. For safe and effective drilling, the rigidity of the drill bit and work piece are most important. The shorter the flute length the more rigid the drill. Longer drills must be adequately supported to reduce vibration.

Important information for safe drill bit usage:

• Use protective gloves and glasses and/or face shield at all times
• Clamp the work piece securely
• Select the correct speed and feed
• Use an appropriate coolant or lubricant
• Ensure the shank is securely held. Aviod using worn drill chucks as the drill may slip during use.
• Regrind the point or replace the drill before it dulls, do not force a worn drill.
• When deep hole drilling, withdraw frequently to clear the chips or swarf (deep holes start at 4X the diameter)
• For stainless steel, manganese and high tensile steels, do not allow the drill to swell as it will cause work-hardening. Use a slower speed and heavier feed for these materials.
