The product is a 10-Piece rotary hammer drill bits set.

4-cutter instead of just 2-cutter: harder, tougher and more resistant and durable under heavy loads, for longer life and faster and easier drilling

Range: 0-0.03" graduation: 0.0005"

Made of steel hardened with all metal components, durable satin chrome finish

Made by Laser-Cut technology, much better than traditional punching process. Punching always has negative effects on the body of the saw blade like deformation and stress, but Laser-Cut could avoid these problems. So Laser-Cut could reduce vibration and noise, maintain durability and cutting precision, keep the blade running cooler.

The tips are made of professional tungsten carbide with Cobalt 6X, the body is made of high quality Japanese steel SK5. Tungsten carbide tips are carefully welded to each blade tooth using computerized technology to control the exactness of the saw blades. An automated grinding process yields accurate tip geometry to increase the life and performance of the ATB C3 carbide teeth.

Mini 3D 50lb with fine adjustment and 2 magnetic faces (bottom and back) and switch on/off, base size (L x W x H): approximate 1.5 x 1.1 x 1.4 inch / 38 x 29 x 35 mm, total height: approximate 9 inch / 23 cm, clamping hole diameter: approximate 3/8 inch / 9.5 mm. Please see to it that it is mini type with more flexible and portable size, and the magnetic base is 50lb, compared with normal ones (bigger, heavier, and usually 130lb).

2 ways to hold test indicators: with 3/8" stem or dovetail

Measuring range: 0-1" , accuracy: 0.001", with locking clamp and ratchet stop

Metal frame is hardened and Chromeplated, more professional and durable than enamel finished ones, not easy to scratch. Thimble and sleeve are also hardened and Chromeplated, resists rust and reduces glare.

Professional high speed steel M42 (not M3) with cobalt 8% cutting teeth hardened to control the efficient and durable and reliable use on workpieces like sheet metal, Aluminium, wood, plastic, plasterboard, etc.. HSS M42 teeth is particularly good for high strength metal such as stainless steel (HSS M3 ones are good for middle strength metal but not high strength one) because HSS M42 contains cobalt 8%, which raises the hardness of the teeth. HSS M42 is about 20% more durable than HSS M3.

9-piece hole saws: 3/4"(19mm), 7/8"(22mm), 1-1/8"(29mm), 1-3/8"(35mm), 1-1/2"(38mm), 1-3/4"(44mm), 2"(51mm), 2-1/4"(57mm), 2-1/2"(64mm); 4-piece accessories: arbor 9/16"-1-3/16" with shank 3/8"; arbor 1-1/4"-6" with shank 7/16"; arbor adapter 1/2"-20UNF to 5/8"-18UNF; arbor center drill with shank 1/4". Center drills in this kit are all made of real HSS M2 and fully ground, while a lot of bi-metal hole saw kits are with low grade HSS center drills roll-forged.

Made of real steel hardened, professional and quality dial indicator (weight: 0.4lb) , totally different from light Aluminium one (weight: 0.23lb): heavier and stronger, then more durable, not so easy to be deformed, more shock-proof, professional quality and industrial use

All finished dial indicators are inspected 100% piece by piece to control the accuracy

Made of real stainless steel hardened Chromeplated, fine ground and polished, each product has a serial number to control the quality

Professional precision measuring tool for industrial use (particularly on metal workpieces), totally different from DIY hand measuring one (like any carbon steel caliper, which is not good to measure metal workpieces bacause of the low hardness)

Dial test indicator with Range: 0-0.03" graduation: 0.0005", Made of steel hardened with all metal components, durable satin chrome finish

Dial test indicator with 2 Steel Dovetail Clamps 3/8'' and 5/32'', dovetail mount on top and back and front for all-around positioning, 2 ways to fix on the magnetic base: stem (3/8" or 5/32") or dovetail (top or back or front)
