KYK Tools Feedback Thread

The one on top just snapped which sent my hand into a metal spike...





I thought it was just a fluke so i bought another one. It snapped as well....

nuff said... they're cr*p!!!

[yebo]

don't you just wish you were in the US so you can sue them for gadzillions of dollars!

I got some KYK chrome-vanadium wrenches... they work great.

Ganyan po talaga mga die cast wrenches (even other brands).... Get the chrome-vanadium ones lalo na pag medyo high-torque yung gagamitan mo....

I'm also tired of those broken die cast ones (i already broke a number of them as well)... kaya pag bumibili ako ng mga bago, di baleng mas mahal by 3x to 4x, basta sure akong mas matibay.

[Psylocke]

they are chrome vanadium but apparently not drop forged so they're cast.... thanks for pointing that out i didn't notice it...

[OTEP]

Baka ganyan din ang tools sa Honda Casa.

Nasasabugan na din ako ng KYK wrench. Always wear eye protection.

ay sorry.... I forgot to mention drop forged chrome-vanadium nga dapat, not the die cast ones.

[Horsepower]

The best brand of tools we have bought are Ridgid and Bosch. I have several KYK stuff and they work great. Be careful of imitations tho.

[EssB]

If for long term use naman and you want to be sure na matibay, you might want to try Draper or Daikin, etc...

kung kaya lang sana ng budget.... tsaka weekend DIYer lang naman ako eh...

What's the diff between a die cast from a drop forged tool???

I may sound like a fool but it looks like it's just a case of semantics to me...

[nugundam93]

die cast...roughly analogous to pouring gelatin onto a mold and letting it solidify, although in this case, it uses a die/mold to form the shape though pressure.

drop forged...uses the principle of forging to better align the metal grains for a tougher product with less weight.

[badkuk]

pasensiya na sir, medyo na curious ako...

metals have grains? pano po ung process of aligning the grains, physical, chemical, etc?

pag drop forged, it sorta compresses the metal more, kaya mas matibay?

would it be somewhat similar to blacksmithing?

[ARB]

what did you use it for?

could the close/box wrench for those hard to remove bolts

[nugundam93]

short info muna about forging:

Forging is the working of metal by plastic deformation. It is distinguished from machining, the shaping of metal by removing material, such as by drilling, sawing, milling, turning or grinding, and from casting, wherein metal in its molten state is poured into a mold, whose form it retains on solidifying. The processes of raising, sinking, rolling, swaging,drawing and upsetting are essentially forging operations although they are not commonly so called because of the special techniques and tooling they require.

Forging results in metal that is stronger than cast or machined metal parts. This is because during forging the metal's grain flow changes in to the shape of the part, making it stronger. Some modern parts require a specific grain flow to ensure the strength and reliability of the part.

drop forged:

The workpiece, say a wrench, is created by hammering a piece of hot metal into an appropriately shaped die. The metal (in some default, easily produced shape like a rod or brick) is heated and placed on the bottom part of a die. The top part of the die then drops onto the piece, which gives the forge its name. The die may drop under gravity or be powered, but in all cases drop forging involves impact. The force of the impact causes the heated metal to flow into the shape of the die, with some metal squirting out of the thin seams between the die covers. This thin metal is called "flash" and has to be cut away in the next stage of processing. The drop-forged pieces usually also need further processing, like machining and polishing of working surfaces, in order to comply with stricter tolerances than forging alone can provide, and to present a good finish.

related info, same link:

Closed-die forging is more expensive for mass production than is casting, but produces a much stronger part, and is therefore used for tools, high-strength machine parts and the like. In particular, forgings are commonly used in automotives, where a high strength requirement is demanded of the part, with a contraint on the mass of the part - in short, a high strength-to-mass ratio. Forged parts are more suitable for mass production. The process of forging a part is becomes cheaper with higher volumes. For these reasons forgings are used in the automotive industry, usually after some machining. One particular variant, drop forging, is often used to mass produce flat wrenches and other household tools.

^^^ in this case, drop forging qualifies under closed-die forging.

and for die casting:

Die Casting is the process of forcing molten metal under high pressure into the cavities of steel molds...

badkuk, yeah, same principle as blacksmithing yung forging.

[LHV]

before ako ang nabili ng tools para sa planta namin, mahirap talaga yung cheap tools, lalo na yung wrench hindi fit sa bolts, ang medyo ok lang na mura eh yung screwdrivers pero mag Stanley ka na lang din, ganda ng fit ng phillips nila hindi nakakabilog para sa akin same lang ng Facom which is 6x more expensive, pero cutting tools buy the best you can afford

[raine]

Try mo Snap-on medyo mahal lang but with lifetime warranty, sa may boni ave. meron outlet,

[t2erns]

mahirap din mahuhusay na brand pag sa talyer,we used to have husky and craftsman kaso unti-unti ninakaw, kaya ngayon yung cheap na lang

Thanks for the info guys!!!!

By the way...

Psylocke, I think you need a stitch or 2 with that laceration of yours. Are your tetanus shots up to date???

[Psylocke]

Stitches? Mutants don't need stitches hehehe magaling na nga eh hirap lang ako mag-mountain bike di ko ma-grip yung handlebars with my pinky...

Thanks!

Basically you forge something by squeezing it into whatever shape it's supposed to be, as opposed to casting which is letting it harden in a mold. Sort of intuitive why the forged stuff is tougher.
