Description

Hand Tap set of 3 pieces DIN 352 HSS-G - BSW 3" x 3.5

You use Hand Tap set of 3 pieces DIN 352 HSS-G - BSW 3" x 3.5 to generate threads during manufacturing, maintenance, or repair work. Correct results depend on matching the tool to the specified thread designation and keeping the tool aligned to the axis.

BSW means British Standard Whitworth, an inch based Whitworth thread form found on legacy equipment and repair work. DIN 352 indicates the referenced standard family or tool standard named in the product designation. HSS-G indicates high speed steel with a ground execution, typically chosen for controlled cutting and consistent geometry.

Application

Hand Tap Set use in repair and small batch work, including service workshops and mechanical engineering.
Thread production on prepared holes or blanks where alignment is controlled by a holder, guide, or machine spindle.
Process: manual driving or assisted driving depending on your holder and machine setup
Use: thread cutting, re tapping, and thread cleaning depending on condition
Use suitable lubrication and remove chips regularly so cutting edges do not pack up.
Thread system context: match the tool to the BSW specification stated on the part or drawing.

Note Clean threads and tools before use, apply suitable lubrication for cutting operations, and stop if resistance rises sharply.

Benefits

Direct selection by thread designation such as BSW when stated reduces setup mistakes.
Suitable for workshop processes where alignment and controlled engagement are practical priorities.
Supports consistent thread quality when you use steady feed and lubrication.
Works well for maintenance tasks where parts must be reworked to the drawing requirement.

Drawbacks

Not suitable for materials or hardness outside the typical range for the named tool material and execution.
Not intended for high performance production without a validated process and rigid machine conditions.

Step by step

Prepare the hole or existing thread so entry is clean and burr free.
Select a suitable holder and ensure the tool is aligned square to the thread axis.
Apply suitable cutting lubricant and start the cut with steady rotation.
Maintain even feed without side force so the tool follows the axis.
Reverse briefly to clear chips from the flutes, then continue with controlled engagement.
Stop when required depth is reached, then back the tool out completely.
Clean the thread and tool, then protect the tool from corrosion for storage.
