Quantum PM4 taps are manufactured from PM4 powdered metal with ANSI shanks and DIN 371/376 dimensions, available in Class 2B (imperial) and Class 6H (metric) threads. The taps are offered in three configurations: spiral point (Quantum-SPX) for through holes, spiral flute (Quantum-SFX) for blind holes, and TiN coated roll form (Quantum-RFX) for cold forming. PM4 powdered metal blanks from 1/4″ to 1″ in Table 302A dimensions are available for 24 to 48 hour deliveries.
What are Quantum PM4 taps made from?
Quantum PM4 taps are manufactured from PM4 powdered metal and offer superior wear resistance and exceptional toughness for greater performance than regular high speed steel. The powder metallurgy and unique geometry ensure consistent performance, superior thread quality and excellent tool life for lower costs. Quantum taps are successful in materials up to 38RC hardness.
What dimensions and standards do Quantum taps follow?
Quantum taps have DIN lengths with ANSI shanks and square, which gives a longer tap with CNC reduced neck design. This style enhances chip evacuation and cutting fluid reaching the threads for reduced friction, galling and heat buildup. The design also reduces contact between the tap and the work piece. Quantum taps withstand high heat and the stress associated with high speed CNC production.

What are Quantum-SPX spiral point taps?
Quantum-SPX spiral point taps are designed for efficient threading of through holes. The shearing action of the spiral point provides a free cutting action and ejects the chips ahead of the tap eliminating chip problems and chip damage to the threads.
What are Quantum-SFX spiral flute taps?
Quantum-SFX spiral flute taps are designed to lift the chips from the hole in blind hole applications eliminating the chips damaging threads or causing the taps to break.
What are Quantum-RFX roll form taps?
Quantum-RFX roll form taps eliminate chip removal and allow for higher machining rates through the process of cold forming rather than thread cutting. Quantum RFX roll form taps can be used in a wide range of ductile materials. The lube grooves act as a conduit for lubricating during tapping operations, especially beneficial in blind hole threading. Quantum-RFX roll form taps are TiN coated adding increased lubricity and thread quality.
