Exterior Taps The correct plumbing supplies are essential for successful drainage and valves are a vital component to ensure that a flow of liquid is regulated, directed or controlled. Toolstation supplies an extensive variety of valves that connect to numerous types of pipes. Make sure this is fitted on a clean, straight, undammaged section of pipe. No dents, no paint or scratches. I used very fine wire wool to rub the pipe smooth, which is available from screwfix. Make sure the cutter is screwed out below the level of the seal before fitting the clamp so the seal seats before the cutter presses into the pipe. Purchased a 15mm piping self cutting tap and assumed that on purchasing 22mm adaptor, it would be a matter of changing ofer fittings, BUT the thread on the 22mm adaptor is different, Therefor of no good whatever.
Non-corrosive and easy to clean, stainless steel is revered both for its strength and its appearance. A go-to material in transportation, consumer goods, food production, construction, and a variety of other industries, stainless steel plates and tubes are popular work materials for drilling and tapping applications. While a common material, drilling and tapping stainless steel requires the proper tools and precautions to ensure efficient and safe operations. Before discussing the proper taps and drills for working with stainless steel, it is important to understand the material’s characteristics in order to extend tool life and achieve quality workmanship.
Properties of Stainless Steel
Though noted for its strength, stainless steel does not rank among the hardest materials you are likely to encounter in your metal work. The problem is that many stainless steels – 304 and 316 in particular – can get harder and tougher to cut as you work if the cutting tools are improperly applied. This phenomenon, known as work hardening, occurs because of the heat generated if the incorrect speed and feed rates for drilling and tapping stainless steel are applied. If the cutting speed (RPM) is too high and the feed is too slow, the drill will “rub” rather than cut, which will create heat and actually toughen the work material. Adding to the challenge, the heat is generated as work progresses, hardening the bottom and sides of the hole just before they are about to be cut. Drilling stainless steel that is susceptible to work hardening makes the drill work harder, shortening its life through wear and increasing the chance of breakage. And because the material stays hard, it has the same effect on taps employed later in the machining process.
Stainless steel possesses a few other traits that affect the way it should be drilled and tapped:
- Ductility – Austenitic, duplex, and other stainless steels stretch more than most other metals when subjected to tensile stress. They “give” or yield to a drill’s pressure before the tool’s cutting edges can gain purchase. This makes it difficult for the tool to break off chips.
- Strength – Even when the drill or tap bites into some stainless steel varieties, the material’s strength resists the forming of chips, causing built-up edges which lessen hole quality and thread formation.
- Low Thermal Conductivity – The material cannot dissipate heat quickly. The high temperatures generated when drilling or tapping stainless steel remain concentrated in the tool tip, which can cause it to deteriorate. High-speed steel components will lose hardness and carbide taps and drills can develop microscopic cracks on cutting edges when exposed to high, sustained heat.
Keys to Drilling and Tapping Stainless Steel
As discussed above, stainless steel’s great strength and elasticity causes difficulty in chip breaking, formation, and evacuation. Chips clogging in the flutes typically will cause catastrophic tool failure but can also cause the tool and the workpiece to vibrate excessively which is not good for the cutting tool, hole finish, and thread quality. Securely clamping the workpiece and stabilizing the drill in the correct tool holder will help, as will reducing the tool overhang as much as possible.
Using sharp tools also will help reduce vibrations as well as work quality and heat reduction. But running work at proper feeds and speeds is the best way to cut clean holes and tap stainless steel most efficiently. While narrow-diameter drill bits must maintain a minimum speed to be effective, wider bits, especially when used to bore deeper holes, must be dialed back to lessen the risk of breakage. However, the recommended surface footage per minute (SFM) must be maintained regardless of the drill diameter. While different applications and grades of stainless steel require different speed and feed parameters, maintain the recommended speed. Feed rates can be relatively high, so long as you’re careful to guard against breakage and tool weakening owing to high heat. High feeds will help the tool cut, evacuate chips and to cut through work-hardened material. Maintain the feed rate throughout the process and take care not to allow the tool to dwell or rub against the side of the hole. This procedure will allow the heat to escape with the chip and not build up in the tool or the workpiece. Ideally the goal is to see a chip that has turned blue. A black or brown chip indicated there is too much heat; reduce your speed (SFM) and increase the feed. A shiny chip indicated the lack of heat; increase the speed and feed.
Heat is the enemy here, so it may be advisable to drill stainless steel in stages, allowing time in between for the tool to cool down. Make it a series of sprints instead of a marathon. The drilling sessions should be short, with adequate pressure. Be sure to keep the drill at full feed when exiting and re-entering the hole.
Don’t forget to lubricate while working with stainless steel. Flood throughout the work, if possible. If not, stop regularly to reapply oil or coolant.
Metal Cutting Tools for Stainless Steel
Tool geometry, design, and metallurgy have created drills and taps for stainless steel that incorporate features that make the work go more smoothly:
- Cutting Edges – Split points have cutting edges that are often sharpened at more acute, narrow angles at the tip, which prevent the drill from walking. Cutting angles of 135 degrees cut thinner chips that can be evacuated more easily.
- Tool Metal – The higher purchase price for cobalt drills may prove a worthwhile investment for those who work extensively in stainless steel. The cobalt alloy runs completely through the bit – it’s not merely a coating - so they maintain cobalt’s hardness and heat-resistant properties through multiple sharpening’s. High-speed steel tools can be used on stainless steel, but shorter drills are the most effective as they are less susceptible to deflection. The best HSS drills for stainless steel are alloyed with tungsten or molybdenum. Carbide tools can be used on long runs without the need for frequent tool changes, making them ideal drills and taps for stainless steel.
- Coatings – Coating drills in titanium nitride makes them more resistant to heat. They can stand up to the high feed rates that stainless steel requires, while increasing hole integrity and a smooth finish.

How Does A Hot Tap Work?
Hot tapping is also known as wet tapping. It is a way to tap into a water line while it is under pressure and add a line, drain the system or add a Thermowell or sensor. You place a hot tap service saddle or sleeve onto the line. You add a valve and test the connection under pressure with a hydrostatic pump. Then you place the hot tap machine onto the value through a water tight packing gland, open the valve and lower the cutter and retention pilot down until it touches the pipe. You then drill into the pipe manually or with an electric or air driven unit that cuts a hole in the pipe. The retention pipe grabs the cut out coupon so it doesn’t fall down into the pipe where it could cause a problem down he line. You then retract the cutter and pilot up into the hot tap machine, close the valve and you have completed a hot tap.
