Popular Dormer Products

Dormer's taps and dies range includes essential threading tools for professional applications. Their hand tap sets feature taper, second, and plug taps for complete thread cutting operations, while spiral flute taps excel in through-hole applications by efficiently evacuating swarf. For die cutting applications, Dormer's circular split dies offer adjustable thread diameter control with excellent chip clearance. The brand's HSS-E cobalt taps are particularly valued for machining stainless steel and heat-resistant alloys, whilst their machine taps deliver consistent performance in CNC and automated production environments.

Frequently Asked Questions

What materials can Dormer taps and dies cut threads in?

Dormer taps and dies are designed to thread a wide variety of materials including mild steel, carbon steel, stainless steel, aluminium, brass, copper, and cast iron. Their cobalt steel variants are specifically formulated for harder materials and heat-resistant alloys where standard HSS tools struggle.

How do I select the correct Dormer tap for my application?

Selection depends on several factors: the material being tapped, whether it's a through-hole or blind hole, and your machinery type. Hand taps are ideal for manual operations and repair work, spiral flute taps suit through-holes, and spiral point taps work best for blind holes. Consider the thread standard required (metric, BSW, UNC, etc.) and hole depth when making your choice.

What's the difference between HSS and HSS-E cobalt taps?

HSS (high-speed steel) taps are suitable for general-purpose threading in common materials. HSS-E cobalt taps contain 5-8% cobalt, providing superior heat resistance and hardness, making them essential for threading stainless steel, titanium, and other difficult-to-machine materials where standard HSS tools would wear prematurely.
