Khob Drill Bits: Ib Daim Ntawv Qhia Tag Nrho rau Hom, Yuav Siv Li Cas, Zoo & Cov Lus Qhia Yuav

Hom iav Drill Bits

Xaiv qhov zoo ntawm iav laum me ntsis nyob ntawm koj cov khoom thiab qhov project. Nov yog plaub qhov kev xaiv nrov tshaj plaws, nrog rau lawv lub zog thiab kev siv zoo tagnrho:

1. Pob zeb diamond-coated iav laum khoom

Hom ntau yam thiab siv dav tshaj plaws, cov khoom siv pob zeb diamond-coated muaj cov hlau ncej (feem ntau yog high-speed steel los yog carbon steel) coated nyob rau hauv me me pob zeb diamond hais - ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws nyob rau hauv lub ntiaj teb no. Lub pob zeb diamond txheej grinds tam sim ntawd iav, tsim du, nti-dawb qhov.

Cov yam ntxwv tseem ceeb: Muaj nyob rau hauv lub shank ncaj (rau cov qauv xyaum) lossis hex shank (rau cov tsav tsheb cuam tshuam), nrog txoj kab uas hla ntawm 3 hli (1/8 ") txog 20mm (3/4"). Ntau tus muaj cov lus qhia tapered los coj me ntsis thiab tiv thaiv kev swb.
Qhov zoo tshaj plaws rau: Txhua hom iav (nyias, tuab, tempered), ceramic vuas, porcelain, thiab marble. Zoo meej rau DIY tej yaam num xws li txhim kho iav pob qhov rooj los yog chav dej pobzeb fixtures.
Pro Lub Tswv Yim: Saib rau "electroplated pob zeb diamond txheej" (ntau dua li cov xim pleev xim) rau lub neej ntev.

2. Carbide-Tipped iav Laum khoom

Carbide-tipped khoom muaj ib tug tungsten carbide ntsis brazed rau ib tug hlau ncej. Txawm hais tias tsis nyuaj li pob zeb diamond, carbide tseem tawv txaus los txiav los ntawm iav thiab ceramic, ua cov khoom no yog lwm txoj hauv kev siv nyiaj txiag.

Cov Ntsiab Lus Tseem Ceeb: Feem ntau muaj lub tshuab raj raj tsim kom tshem tawm cov plua plav thiab cov khib nyiab, txo cov cua sov. Txoj kab uas hla ntawm 4mm (5/32 ") mus rau 16mm (5/8").
Qhov zoo tshaj plaws rau: nyias iav (xws li, iav iav, daim duab thav duab) thiab cov iav tsis-tempered. Tsis txhob siv cov iav tuab lossis tempered - lawv yuav ua rau tawg.
Pro Tip: Siv cov no rau cov haujlwm me me, qee zaus; lawv hnav sai dua pob zeb diamond me ntsis nrog hnyav siv.

3. Spear Point iav Laum khoom

Kuj tseem hu ua "cov khoom siv pobzeb," hmuv taw tes cov khoom muaj qhov ntse, taw qhia (zoo li tus hmuv) nrog ob txoj kab txiav. Lawv tau tsim los pib qhov nrawm nrawm thiab sib npaug, txo qhov kev pheej hmoo ntawm kev swb.

Cov yam ntxwv tseem ceeb: Ua los ntawm carbide lossis pob zeb diamond-coated steel, nrog luv luv, ruaj khov ncej kom txo tau wobble. Feem ntau yog 3mm-10mm nyob rau hauv txoj kab uas hla.
Qhov zoo tshaj plaws rau: cov vuas ceramic, iav mosaic daim, thiab qhov me me (xws li, rau cov kab grout lossis cov khoom me me).
Pro Tip: Lub hmuv taw tes yog qhov zoo tagnrho rau kev kos lub qhov chaw nruab nrab-tsis xav tau cov cuab yeej xuas nrig.

4. Hollow Core iav Laum khoom

Hollow core bits (los yog "qhov saws rau iav") yog cylindrical nrog pob zeb diamond-coated ntug. Lawv txiav cov qhov loj los ntawm kev tshem lub "plug" ntawm iav, tsis yog sib tsoo cov khoom.

Cov Nta Tseem Ceeb: Txoj kab uas hla ntawm 20mm (3/4 ") txog 100mm (4"), ua rau lawv zoo meej rau cov haujlwm loj. Lawv xav tau ib phau ntawv qhia (xws li lub khob nqus dej) kom nyob hauv nruab nrab.
Qhov Zoo Tshaj Plaws Rau: Cov qhov loj hauv iav tabletops, qhov rooj da dej, lossis cov thoob dej yug ntses. Kuj tseem ua haujlwm rau cov plooj (porcelain sinks) tuab.
Cov Lus Qhia Pro: Siv lub laum qeeb qeeb (500-1,000 RPM) kom tsis txhob ua kom sov lub khob.

Cov yam ntxwv tseem ceeb los nrhiav hauv iav Laum khoom

Tsis yog txhua lub iav laum khoom tsim tau sib npaug. Cov yam ntxwv no txiav txim siab seb qhov ua tau zoo npaum li cas thiab nws kav ntev npaum li cas:

1. Txheej zoo

Rau cov pob zeb diamond me ntsis, electroplated pob zeb diamond txheej yog tsis-negotiable-nws bonds pob zeb diamond ncaj qha mus rau ncej, xyuas kom lawv tsis flake tawm. Pheej yig "painted" pob zeb diamond txheej hnav tom qab 1-2 siv. Rau cov khoom siv carbide, nrhiav lub ntsej muag polished carbide kom txo kev sib txhuam.

2. Shank Tsim

Ncaj Shank: Haum rau feem ntau tus qauv xyaum chucks (3/8 "los yog 1/2"). Zoo tagnrho rau corded thiab cordless xyaum.
Hex Shank: Tiv thaiv kom tsis txhob ntog hauv kev cuam tshuam cov tsav tsheb, ua kom yooj yim rau kev siv lub siab ruaj khov. Zoo rau cov ntaub ntawv tawv zoo li tuab ceramic.
Shorter Shaft: Txo wobble, uas yog qhov tseem ceeb rau iav (txawm tias me me txav tuaj yeem ua rau tawg). Npaj rau shafts 50mm-75mm ntev rau feem ntau cov haujlwm.

3. Tswv yim Geometry

Tapered Tip: Qhia me ntsis rau hauv lub khob yam tsis muaj swb, zoo meej rau cov pib tshiab.
Flat Tip: Faib siab sib npaug, zoo tagnrho rau cov iav tuab lossis marble.
Spear Tip: Pib qhov sai sai, zoo rau cov vuas qhov uas qhov tseeb yog qhov tseem ceeb.

4. Cua txias nta

Cov iav tawg thaum nws overheats, yog li nrhiav cov khoom nrog:

Spiral Flutes: Tshem tawm cov plua plav thiab tso dej (tus neeg ua haujlwm txias) kom ncav cuag qhov txiav.
Hollow Core: Cia dej ntws los ntawm qhov chaw, ua kom me ntsis thiab iav txias thaum txiav loj.

Yuav Siv Cov Khob Drill Bits li cas (Step-by-Step Guide)

Txawm tias qhov zoo tshaj plaws iav laum me ntsis yuav tsis ua haujlwm yog tias siv tsis raug. Ua raws li cov kauj ruam no kom tsis txhob tawg thiab tau qhov zoo meej:

1. Sau koj cov cuab yeej

iav laum me ntsis (xws li koj lub qhov loj thiab cov khoom siv).
Corded los yog cordless laum (teeb rau qis-500-1,000 RPM).
Dej (hauv lub raj mis los yog lub tais me me) kom txias me ntsis.
Masking daim kab xev (kom kos lub qhov thiab tiv thaiv plam).
Clamp los yog suction khob (kom tuav lub khob rau hauv qhov chaw).
tsom iav thiab hnab looj tes (tiv thaiv iav shards).

2. Npaj iav

Ntxuav lub iav kom tshem tawm cov av los yog roj-cov khib nyiab tuaj yeem ua rau me ntsis plam.
Siv ib daim kab xev npog rau ntawm thaj chaw uas koj xav tau lub qhov. Kos qhov nruab nrab ntawm lub qhov ntawm daim kab xev (cov kab xev txo cov chipping thiab pab me ntsis nyob rau hauv txoj kev).
Khaws lub khob nrog lub clamp (yog tias nws yog ib qho tiaj tiaj, zoo li pobzeb) lossis lub khob nqus dej (rau iav nkhaus, zoo li lub vase). Tsis txhob tuav lub iav los ntawm tes - tam sim ntawd txav mus ua rau raug mob.

3. Laum lub qhov

Sau ib lub raj mis tsuag nrog dej thiab smost daim kab xev thiab me ntsis. Dej yog qhov tseem ceeb - nws txias me ntsis thiab iav, tiv thaiv overheating.
Teem koj lub laum rau qis qis (kev kub ceev ua kom muaj cua sov ntau dhau). Tuav lub laum ncaj (perpendicular rau iav) kom tsis txhob wobble.
Siv lub teeb, ruaj khov-cia me ntsis ua haujlwm. Tsis txhob thawb hnyav! Kev siab dhau yog qhov # 1 ua rau cov iav tawg.
Tso tseg txhua 10-15 vib nas this kom tsuag dej ntau dua thiab tshem cov plua plav tawm ntawm lub qhov.
Thaum me ntsis pib tawg los ntawm lwm sab (koj yuav hnov tsis tshua muaj zog), qeeb qeeb dua. Qhov no tiv thaiv iav los ntawm chipping nyob rau sab nraum qab.

4. Ua kom tiav lub qhov

Thaum lub qhov ua tiav, tua lub laum thiab maj mam tshem cov me ntsis.
Yaug lub khob nrog dej kom tshem tawm cov plua plav. Tshem tawm daim kab xev nplaum.
Rau cov ntug du, siv cov ntawv xuab zeb zoo (400-600 grit) kom maj mam xuab zeb ntawm lub qhov npoo (ntub-xuab zeb ua haujlwm zoo tshaj plaws kom tsis txhob khawb).

Qhov zoo ntawm kev siv cov iav tshwj xeeb laum khoom

Vim li cas ho tsis siv tus qauv hlau laum me ntsis ntawm iav? Nov yog vim li cas cov iav tshwj xeeb cov khoom tsim nyog rau kev nqis peev:

1. Tiv thaiv kev tawg & tawg

Cov khoom txheem txheem muaj cov hniav ntse, txhoj puab heev uas tom rau hauv iav, ua rau muaj kev ntxhov siab thiab tawg. Cov iav laum cov khoom siv maj mam txhuam (pob zeb diamond lossis carbide) kom zom cov khoom maj mam, txo kev ntxhov siab ntawm lub khob.

2. Ua kom huv, meej qhov

Pob zeb diamond thiab carbide coatings kom du, txawm lub qhov uas tsis muaj ragged npoo. Qhov no yog qhov tseem ceeb rau cov haujlwm pom (piv txwv li, iav txee, qhov rooj da dej) qhov chaw zoo nkauj.

3. Ua haujlwm ntawm ntau yam khoom siv

Feem ntau cov iav laum khoom (tshwj xeeb yog cov pob zeb diamond-coated) txiav los ntawm ceramic, porcelain, marble, thiab pob zeb. Qhov no txhais tau hais tias ib qho me me tuaj yeem tswj koj chav dej pobzeb thiab iav iav qhov project - tsis tas yuav yuav cov cuab yeej cais.

4. Kev ua haujlwm ntev ntev

Pob zeb diamond-coated cov khoom tuaj yeem txiav 50+ qhov hauv iav ua ntej yuav tsum tau hloov, thaum cov khoom txheem yuav tawg tom qab siv ib zaug xwb. Qhov no txuag nyiaj dhau sijhawm, tshwj xeeb tshaj yog rau cov kws tshaj lij lossis cov DIYers nquag.
