Product Introduction:

The PC series with of the straight flute drill is one of most suitable tool for materials with short chips such as cast iron, silicon-aluminum alloy and etc. It has excellent self centering capability which will be able to machine with high efficiency and the hole precision up to H7. The point angle equals to 140°which makes to the optimized drill tip structure for high standard cutting performance. It is determined by depth of hole, guide bushing length and regrinding allowance. The longer the flute is, the lower the drill rigidity is, which greatly affects tool life. So it is recommended to minimize the flute length as much as possible when other requirements are met. The minimal flute length generally is depth of hole plus 1.5 times of the hole diameter. Our PC series can bring high positional accuracy, high linearity and good surface finish to our users.

Cutting parameters for PC series straight flute drill (internal coolant)

These conditions are applicable for cutting depth under 15D.

Machining tips:

Inclined face and curved face drilling:

When drilling inclined face or curved face, feed rate should be reduced as recommended:

Surface with a large inclined angle should be pre-treated. Face milling should be conducted before drilling.
