Kaize, kung hinde screwed on yung chuck, pinapalo lang yan upwars pero hinde dun sa colett nya. gamitin mo kahoy pukpok mo sa kahoy and the kahoy tumatamadun sa gilid ng colett, sa housing ng chuck. Yung colett ay yung 3 iniipit and bit.

^ I think they're referring to this sir. guide, para laging 90 degrees ang butas.

BTW, gumagamit ako ng Drill Press to drill PCB lalo na kapag FR4 material at maraming butas and especially kapag double sided. medyo matrabaho magbutas ng FR4 kung 'yung mga maliliit na hand drill ang gamit. eto ang reason kaya 'yung mga drill bit ko sa bahay is mostly HSS with 1/8" shank. pwede sa drill press, pwede rin sa hand held high speed rotary tool (like Dremel, pero Black and Decker gamit ko).

I use this model and works fine for me. Definitely a useful tool for hobby work.

Pjarina sis. speed doesn't really matter to me pag hi speed dril lbit naman nakakabit. Howevr, tis is for thin wood./ pag makapal, uusog na yung wood kaya you have to slow down. Di mo naman pwdeng less pressure like for metal sheet drilling dahil nakabaon na and bit mo sa wood. Yung fan belt ay nililipat. Mailiit sa motor, malaki sa drill.


     By the way, I have 3 electric drills na sira na ang rechargeable battery.  Gamit ko ay yung SLA pang lantern na 6V, na 4AH yun! nakatali sa ilalim. Gumawa ako ng small adaptor charger para dito. Works fine.  I have a Craftsman binili ko sa Walmart sa Tatenoon. Di ko ginagamit. $50 ang bili ko na may case siya. Ok pa battery at pwede naman pa repack sa ELFOH sa Raon. Or sub C ata, we can replace it. If somewant wants it for P1500, I will let it go. Yung mga iba, pwede sa P900. Excellent to make into PCB drill press. Use a small car shock absorber. Remove the fluid, movable ang shaft nun.Attach the electric drill dun.

depende sa material na bubutasan may iba't-ibang klase ng drill bits (material, coatings, etc).
pag stainless steel kailangan talaga mabagal lang at, at least, cobalt steel alloy,
puede rin ang high speed steel pero di magtatagal ang bits.
yung iba gumagamit ng cutting fluid/lubricant/coolant para tumagal ang mga bits.

kadalasan mas maraming gumagamit ng high carbon steel dahil sa mas mura kumpara dun sa iba.
ang nangyayari nga lang bili lang ng bili ng bago pag mapurol na.

^ o kaya naman hahasain ng hahasain hanggang maubos 'yung talim. ;D

'yung talim na pangkahoy talaga merong mas maliit at matulis na dulo (centering point ata tawag doon).

kung hindi naman sobrang liit ng bits puede na rin yung portable drill bit sharpener,

Mga sis itong paghahasa sa drill bit is being done sa talyer namin. Di masyado ok pero pag medyo matigas ang trabaho at napurol ang bit gina grind na lang in an angular position na parang sa orig. Though di ganun ka okey ...wag lang uminit ng todo during grinding para wag mawala ang treatment ng metal pede na kesa bibili ng bagong bit for the same price ng trabaho. Use lang ung lathe machine at bato ng rotary grinder
