Tungsten Carbide Spiral Tap Introduction

Details: Category: Tungsten Information; Published on Friday, 18 July 2014 18:06; Hits: 673

Tungsten carbide spiral grooves are the chip spiral shape, depending on the rotation of the tungsten carbide screw-tap that can be divided into left and right helical coil. When left-handed spiral flute tap-tapping down the rows of cuttings, suitable for through-hole tapping processing; discharged tap tapping right-handed spiral upward chip, suitable for blind hole tapping.

Tungsten carbide spiral tap processing characteristics are the followings: firstly, it can be tapped to the blind holes’ lowermost; secondly, it will have no tapping remains; thirdly, it has good machinability.

Tungsten carbide spiral flute tap is the most commonly used, according to the different conditions using different helix angle, it is common right-handed 15° and 42 °. Generally the larger the helix angle, the better the performance chip.Suitable for blind hole machining. When through-hole machining is not the best choice.

Tungsten Carbide Hand-taps& Machine-taps’ Introduction

Details: Category: Tungsten Information; Published on Friday, 18 July 2014 17:59; Hits: 620

Tungsten carbide hand-taps refers to carbon tool steel or alloy tool rolling (or incisors) taps for hand tapping; there is a tungsten carbide machine-taps, usually refers to high-speed steel teeth tap for tapping on the machine. However, in production, the two are also used interchangeably. Standard common thread cutting taps. China is customary to manufacture high precision high-speed steel teeth called tungsten carbide machine-taps, the carbon tool steel or alloy tool steel roller teeth (or incisors) called tungsten carbide hand-taps, actually both the structure and works basically the same.

Typically, the taps composed of the working portion and a shank portion. Work part is divided cutting portion and calibration part, the former mill has cut cone, shoulder cutting work, which is calibrated to the size and shape of the thread.

Distinction Between Tungsten Carbide Hand-taps& Machine-taps

Details: Category: Tungsten Information; Published on Friday, 18 July 2014 18:01; Hits: 640

Tungsten carbide machine-taps only has one root, its materials are generally high-speed steel (because of the higher cutting speed), the tail is generally no mortise and tenon (of course there are exceptions) is used when cutting through the machine

Tungsten carbide hand-taps generally have two or three, were called a cone. Two cones and three cones, usually only two.Tungsten carbide hand-taps’ materials are generally carbon tool steel or alloy tool steel. And the tail well and tenon. A portion of the cone cutting edge grinding down six, two inverted cone mill cutting part two edges. When used generally by cutting special wrench.

Introduction of Tungsten Walking Fishing Sinker

Details: Category: Tungsten Information; Published on Friday, 18 July 2014 17:57; Hits: 657

The tungsten walking fishing sinker is flat and rectangular. It works well on rocky bottoms, as it lies flat on top of the rocks instead of falling in between them. You can walk this sinker across the bottom and it gets snagged less often than other sinkers. The tungsten walking fishing sinker slides on your fishing line so a fish won't feel the sinker weight when it picks up your bait. The small footprint of the walking sinker on the bottom reduces your chance of snags.

These sinkers are the bread and butter of many live-bait, walleye fisherman. They resemble a rectangle with rounded, outside edges. The top features an eye for the line. This weight distribution positions the sinker with its round edge on bottom, so it will easily glide over rocks, greatly reducing its changes of snagging on the bottom. The semi-flat design also prevents it from rolling along bottom in fast currents.
