Choosing the Right RGC Tool

Why Professionals Use RGC Threading Tools and Drill Bits

• Complete threading solution under one brand — taps, tap wrenches, ratchet holders, and die handles all matched for compatibility
• DIN 1814 tap wrench standard ensures consistent jaw geometry that grips tap shanks securely without slipping or marking
• Both Carbon Steel and HSS hand tap options let shops match tap material to workpiece — Carbon Steel for soft metals and budget threading, HSS for tougher materials and longer service life
• NPT pipe taps cut the standard tapered thread used in Philippine plumbing, pneumatic, and hydraulic systems — essential for legitimate pressure-rated fittings
• TCT Multi-Purpose Bits eliminate the need to swap between masonry, wood, and metal bits during mixed installation work — practical for electricians and HVAC technicians
• AL TiSIN-coated step drill bits with 3 spiral flutes deliver smooth, deburred holes in sheet metal at 2–3× the service life of uncoated step bits
• Ratchet Tap Holder enables one-handed tapping in confined assemblies, on-machine threading, and overhead work where a T-wrench can't be turned

Expert Tips for Hand Tapping with RGC Tools

• Always drill the correct tap-drill size before tapping — for M6×1.0 use 5.0mm; for M8×1.25 use 6.8mm; for 1/4"-20 NC use 5.1mm (#7); using the wrong tap-drill size produces stripped or weak threads, or breaks the tap
• Use cutting fluid every time — even general-purpose cutting oil dramatically extends tap life, reduces effort, and produces cleaner threads, especially in stainless steel where the alloy work-hardens fast
• Hand-tap with a 1-turn-forward, 1/4-turn-back motion to break chips and prevent packing — never force a binding tap; back out completely, clear chips, and restart with fresh cutting fluid
• Match the tap wrench size to the tap — using a No. 4 wrench (M9–M27 capacity) on an M4 tap gives too much leverage and snaps the tap; using a No. 1 wrench (M1–M10) on an M16 tap doesn't provide enough torque and slips

Frequently Asked Questions

What's the difference between Carbon Steel and HSS hand taps?

Carbon Steel hand taps are economical and well-suited for occasional repair threading in soft materials like mild steel, aluminum, brass, and plastic. HSS (High Speed Steel) hand taps are harder, more heat-resistant, and hold an edge significantly longer — making them the better choice for daily production threading and harder materials. For shops that thread regularly, the longer service life of HSS taps justifies the price difference; for occasional repair work, Carbon Steel taps are more cost-effective.

Which RGC tap wrench size do I need?

Match wrench capacity to tap size: No. 1 (M1–M10) for small precision taps, No. 2 (M4–M12) is the most useful all-around size for general shop work, No. 3 (M5–M20) handles medium-to-large taps, and No. 4 (M9–M27) is for heavy threading on large fasteners and structural work. Most shops keep at least No. 2 and No. 3 to cover the typical M3–M20 range. Using the wrong size wrench either snaps small taps with too much leverage or fails to provide enough torque on large taps.

Are NPT pipe taps the same as standard machine taps?

No. NPT (National Pipe Thread Tapered) taps cut a tapered thread that creates a pressure-tight seal as the fitting tightens — used for plumbing, pneumatic, hydraulic, and gas connections. Standard machine taps (NC, metric) cut straight (parallel) threads used for fasteners. NPT taps and machine taps are not interchangeable — using the wrong type results in leaks, loose fittings, or stripped threads. Always confirm whether the application calls for tapered (NPT) or straight (machine) threads.

Can RGC TCT Multi-Purpose Bits really drill through masonry, wood, and metal?

Yes — the tungsten carbide tip (TCT) is hard enough to drill through ceramic tile, brick, and concrete, while the geometry also handles wood, plastic, and mild steel. They are particularly useful for electricians, HVAC technicians, and installers who frequently encounter mixed materials in walls (masonry + wood studs + metal conduit). For dedicated heavy drilling in any single material, specialized bits (masonry hammer bits for concrete, HSS twist drills for metal, brad-point bits for wood) still outperform multi-purpose bits in their specific application.

What does the AL TiSIN coating on the step drill bit do?

AL TiSIN (Aluminum Titanium Silicon Nitride) is a multi-layer hard coating that significantly increases surface hardness, heat resistance, and lubricity compared to uncoated or basic TiN-coated bits. The result is faster cutting, smoother holes, and 2–3× longer tool life — particularly valuable on step drill bits that drill multiple diameters per cycle and accumulate heat quickly in sheet metal and electrical panel work.
