Hand Taps

HSS-G screw taps are suitable for machinable raw materials up to 900 N/mm². The design in HSS-E for hard to machine raw materials up to 1200 N/mm² and vapourised hand screw taps are particularly suited to wear-resistant steels up to 1400 N/mm².
The taps can be distinguished from their thread leads and marking. Pre-cutters (rougher) are marked on their shank with one and middle cutter (intermediate) with two rings. The finished cutter does not carry a ring and is generally not marked.

• Taper (Rougher) = 6-8 Thread pitch
• Plug (Intermediate) = 4-5 Thread pitch
• Bottoming (Finisher) = 2-3 Thread pitch

It is recommended that the finishing cutter should only be used for trimming damaged threads. The rougher, intermediate and finisher can be ordered separately.

Hex Taps

Threading-Bit 1/4″ HexTap S

VÖLKEL-Threading-Bits have been designed for thread cutting using battery-powered screwdriver drills and electric hand drills with right-hand and left-hand rotation. They are also suitable for thread cutting by hand or in a stationary drilling machine.

Multi-Drive Tap HexTap DS

These are special hand taps with two-in-one pre-tap and final cutter. This tool developed by Völkel is particularly suitable for difficult to access areas and for recutting or repairing damaged threads. This tap can be driven from both ends with a ratchet or offset screwdriver, or at the middle part consisting of an external hex, again using an open-ended spanner.

• Hex Shank Taps Metric
• Hex Shank Taps Imperial
• Hex Shank Taps British Pipe Thread

Hex Die Nuts

Hex die nuts are designed for general use on non-abrasive materials up to 800 N/mm², offering easy thread repair with a standard wrench. Made from durable HSS, they are ideal for unalloyed and low-alloyed steel. For tougher, abrasive materials up to 1200 N/mm², HSS-E hex die nuts provide high cutting ability.

• Hex Die Nut Metric
• Hex Die Nut Imperial
• Hex Die Nut British
• Hex Die Nut Pipe Threads
• Hex Die Nut British Pipe Threads

Combined Tap Bits

Combined bits with a 1/4″ hex drive are designed for drilling, tapping, and deburring in one operation. They work with battery-powered or electric hand drills, supporting both right- and left-hand rotation, and are suitable for stationary drilling machines. Ideal for materials like non-ferrous metals and thermoplastics (up to 600 N/mm²), these bits can create through threads up to 1x diameter. They are especially useful for assembly work and small batch production. For best results, ensure the tool and hole axis are aligned, and always use proper cutting oil.

Round Die

HSS round dies are designed for general use on non-abrasive materials up to 800 N/mm², making them ideal for threading unalloyed and low-alloyed steel. HSS-E round dies offer high cutting ability for abrasive materials up to 1200 N/mm², including stainless steel (INOX). Gun-nosed round dies ensure efficient threading with smooth chip evacuation, enhancing performance in various applications.

Square Die

Square dies are designed for threading non-abrasive materials up to 800 N/mm², including unalloyed and low-alloyed steel. Their shape allows for precise thread cutting in manual operations, making them ideal for general-purpose threading tasks.

• Square Die Metric
• Square Die Imperial
• Square Die British Pipe Thread

Die Stock and Tap Wrenches

Tap wrenches and die stocks are essential tools for manual threading operations. Tap wrenches provide a firm grip and precise control for taps when cutting internal threads, while die stocks hold threading dies securely for cutting external threads.
