Straight Flute Hand Taps

Straight Flute Hand Taps

Sometimes referred to as hand taps, straight-flute taps are suitable for general-purpose manual tapping operations with a tap wrench. They have straight flutes along the cutting edge and can be used to tap blind holes and through holes. As the tap is rotated into a hole to create threads, the chips move into the flutes but are not evacuated.

Thread Repair & Maintenance Taps

Use these taps to restore or repair internal threads for a secure fit when installing a male threaded fastener or part.

High Speed Steel with Improved Lubrication Black Oxide Coating

Suitable for use in a variety of materials, these high speed steel taps have a black oxide coating on the surface that increases wear resistance for extended tool life and helps retain lubricants, improving chip flow and performance. The coating is rust resistant and has a black color.

High Speed Steel with Extended Life Titanium Coating

These taps have a TiN (titanium nitride) coating that provides good temperature resistance and wear protection and provides a smooth surface on the tool that prevents chips from sticking to the cutting edge, helping to extend the life of the tool. High speed steel taps are suitable for use in a variety of materials, including steel and nonferrous metals. TiN coating has a gold color.

Powder Metal with Titanium Coating Taps for Cast Iron

Durable powder-metal taps are harder than cobalt steel taps and offer improved wear-resistance in hard or abrasive materials, but they are also more brittle and require a rigid tool setup. They are suitable for high-temperature tapping applications. The TiCN (titanium carbon nitride) coating on these taps has a low coefficient of friction that helps prevent workpiece material from building up on the cutting edge of the tool and provides good wear protection in abrasive or gummy materials. TiCN-coated taps can run at high speeds, but should be used in materials that produce only moderate temperatures when machined and coolant should be used to avoid premature failure. The coating has a blue-gray color.

Cobalt Steel Taps for Hardened Metals

A good choice for demanding tapping applications, cobalt steel taps provide more wear-resistance at higher speeds than high speed steel taps. They are suitable for use on hard materials such as heat-treated steels, stainless steel, and titanium alloys.
