Tap Sets

Sherwood

Each set of Sherwood taps contain one taper, second and plug lead tap:

Sherwood HSS Taper Taps are used to start cutting the thread. They are tapered back from the end 6 to 10 threads before a  fully threaded diameter is reached. This allows the tap to be positioned easily and correctly before it starts to cut the thread.

The Second Tap is used after the taper tap has cut threads into the hole as far as possible. It tapers back 3 or 4 threads before full thread diameter is reached. 

The Plug Tap cuts threads to the bottom of a blind hole. It is only necessary to use the full set of taps when a blind hole is to be tapped.

A set of three Sherwood HSS Taps ideal for the general purpose option for thread cutting in most materials including steel, some stainless steels, cast irons and non-ferrous materials such as Aluminium, Brass and many others.

Metric Coarse HSS Ground Thread Straight Flute Second Taps

Second Tap, M8 x 1.25mm, Straight Flute, Metric Coarse, High Speed Steel, Bright

Tap & Drill Sets

Sherwood HSS Taps are the general-purpose option for thread cutting in most materials including steel, some stainless steels, cast irons and non-ferrous materials such as Aluminium, Brass and many others.

Manufactured with precision ground flutes for producing accurate thread forms, Taps are available in all the popular thread forms and as straight Flute `Hand` Taps in 3 leads, Fluteless, Spiral Flute, or Spiral Point Machine Taps. Taps dimensions conform to ISO529 apart from NPT Forms which conform to ANSI 94.9. Machine Taps have an oxidised finish for best results dissipating the heat build-up associated with these applications. Thread Forms are Class 2 medium fit tolerance.

Sherwood jobber drills are general-purpose drills for steels, cast steel, grey cast iron, malleable cast iron, nickel brass, aluminium alloy and graphite. With precision ground flutes and black finish (W-finish), this is the most common surface finish and is the result of a steam tempering operation in which steam is passed over the product during a controlled tempering cycle, producing a black oxide layer. Black tools are generally recommended for ferrous applications where the oxide layer aids chip flow, helps to dissipate heat by retaining some coolant on the tool surface and also helps to prevent the tool from staining.

Point angle: 118, helix angle: normal, web thickness: standard, relief angle: 10-20, tolerance of diameter: h8, tolerance of shank: f11. Manufactured to BS 328/DIN338RN.

Set contains:
Taps: M3, M4, M5, M6, M8, M10 and M12 (Taper, Second and Bottom).
Tapping Drills: 2.5mm, 3.3mm, 4.2mm, 5.0mm, 6.8mm, 8.5mm and 10.2mm.
