BAER Threading Tools

BAER Threading Tools

Our range of Threading Tools include Taps, Round Dies, etc. A tap cuts threads on the inside of a hole, creating a female surface which functions like a nut, to accept a machine screw or bolt.

Taps can also be used to restore an internal thread that has been damaged or to cut a larger thread in the case of severe damage.
BAER Threading tools from Germany are among the highest quality available

We have the following range available with us:

Short Machine Taps

With a short length and straight flutes, these taps are suitable for blind and through holes.

Suitable for use by hand or Machine tapping.

Go to the BAER Short Taps page.


Hand Tap Sets

The set consists of a rough tap, intermediate tap and a final finishing tap. For Fine threads the set will have two taps.

Go to the BAER Hand Taps page.


Machine Taps SPPT Form B

Suitable for tapping in through holes, the Spiral Point tap profile pushes the cutting chips forward.

Go to the BAER Form B Taps page.


Machine Taps Spiral Flutes Form C

The Spiral Flute tap profile is designed particularly for tapping into blind holes.

The cutting chips flow backwards preventing the hole from clogging up.

Go to the Spiral Flute Taps page.


Machine Taps Straight Flutes Form C

Machine Taps with Straight Flutes are specially designed for use in through and blind holes. The short lead-in chamfer makes that tap universal in application.

The flutes can hold the most part of the chips.

Go to the Straight Flute Taps page.


Thread Forming Taps

The BAER thread Forming Taps are high performance taps that are extremely for quality tapping at high speeds.

Go to the BAER Forming Taps page.


Round Dies

For quality external threads the BAER Round Dies can be considered.

This range provides the user with useful solutions to external threads including LH Dies.

Go to the BAER threading Dies page.


Holding Tools and Accessories

For effective and efficient threads it is imperative to have the correct installation tools.

The BAER range of accessories provide just that.

Go to the BAER Holding Tools and Accessories page.


Troubleshooting guide for tapping

Tapping causes undersized threads

Pitch error
Too small tolerance
Geometry of the tap is not suitable for the material

Tapping causes oversized threads

Cutting speed is too high
Bad running accuracy
Chip jamming in flutes
Incorrect positioning of workpiece or tap
Inconsistent feed of tap
Too high tolerance

Poor thread surface

Cutting speed not suitable
Cooling is not suitable or not existing
Geometry of the tap is not suitable for the material
Core hole too small

Thread break of the thread to be cut

Geometry of the tap is not suitable for the material
Core hole too small
Core hole not deep enough
Chip jamming in flutes
Bad running accuracy
Incorrect positioning of workpiece or tap
Inconsistent feed of tap

Low tap lifetime

Cutting speed not suitable
Cooling is not suitable or not existing
Geometry of the tap is not suitable for the material
Surface treatment/ coating for tap needed
Core hole too small

Tool outbreaks

Geometry of the tap is not suitable for the material
Core hole too small
Core hole not deep enough
Chip jamming in flutes
Bad running accuracy
Incorrect positioning of workpiece or tap
Inconsistent feed of tap
Worn tap

Cold welding on the tap

Cutting speed not suitable
Increase coolant supply


Guide to Taps.

Surface Coatings

In some applications, the performance of taps can be improved by the application of a special surface treatment or coating. The benefits of surface coatings include:

Longer tool life

Tools can be run at higher feeds and speeds

Increased productivity

Lower maintenance costs

Prevent chip build-up

Coatings can increase the life expectancy of the tap by 3 or more times, however the coatings are subject to consistent machining only. These coatings will not correct machining faults.


Titanium Carbonitride — TiCNite (TiCN)

TiCNite is generally used in heat generated applications for longer tap wear life. TiCNite coated taps have a very high surface hardness, over 3000 Vickers (approximately 90 HRc).

TiCNite is harder and tougher than other coating materials, consequently it has high resistance to

edge chipping and abrasive wear. This coating is black/gray in colour and is suitable for all HSS

grade ground thread taps (will soften carbon steel taps).


Titanium Nitride — TiNite (TiN)

TiNite is generally used in abrasive applications for low cutting temperatures such as cast iron, silicon and aluminium. Physical vapour deposition coating with surface hardness around 2300 Vickers (85HRc). This coating is gold in colour, with excellent resistance to cold welding and very good abrasion resistance. TiNite is a good choice for protecting the tap, can achieve a longer life than uncoated taps, lowers friction,

allows smoother cutting and can be used at higher speeds.

When taps are coated with Titanium Nitride, it is better to start at uncoated speeds and slowly build up to a higher speed. This extends tap worklife and avoids breakages.


Tapping Speeds

Tapping speeds depend on many factors, including the machine, the material being tapped, the design of the hole, the lubricant and the style of tap used. There are no exact rules to follow that consider these variables, however the following information can be used to determine a starting point and course to follow to obtain maximum performance.

Coarse thread taps should be run near the low range while higher speeds may be used for fine

threads. The values in the table should be modified according to the following suggestions:

Reduce speeds for:

Large diameters

High percentage of threads

Coarse pitches

Short chamfer taps

Deep holes

Hard metals

Particularly true of spiral flute and straight flute taps, speeds must be reduced as the depth of the hole increases. This is because of the accumulated chip build up and increased friction in long holes

Taps with long chamfers can be run faster in short holes, however in long holes these taps must be run at slower speeds.

The speed for bottoming taps must be lower than Taper or Intermediate taps.

Coarse thread taps in larger diameters must be run more slowly than fine thread taps of

the same diameter.
