Consolidated Toledo Drill

The point of the tap continuously ejects the chips ahead of the tap, eliminating chip disposal problems and thread damage.
Low temperature stress relief that enhances lubricity, reduces friction and increases tap toughness.
They are called "Gun Taps" because they shoot the chips ahead of the tap.

Spiral Point — Titanium Nitride Gun Plug Tap

Titanium nitride coating: increases wear resistance with exceptional lubricity resulting in longer tool life.
The chips are forced out ahead of the tap instead of accumulating in the flutes, as they will with a plug tap.
This coating gives the taps a very high surface hardness to help penetrate tough materials.

Spiral Point Tap Plug
Most common type of power driven tap is the "spiral point plug tap"; whose cutting edges are angularly displaced relative to the tap centerline.

This feature causes the tap to continuously break the chip and eject it forward into the hole, preventing crowding.

Spiral point taps are ideal for machine tapping of through holes or blind holes where there is enough clearance beyond the threaded portion to accommodate the swarf. (fine chips or filings of stone, metal, or other material produced by a machining operation)
