A 1/8-inch drill bit is 0.125 inch or exactly 3.175 mm in nominal diameter. Choose the cutting type for the material, not the size alone.
Verify the cutting diameter, material application, bit category, shank fit, and usable drilling depth before buying.
Compare tapered, straight, extra-long and specialty cutters, then verify diameter, plug length, shank and drill-press compatibility.
Match bearing position to the reference surface, then compare cutting length, shank, diameter, and flute geometry for your routing setup.
Match standard or cobalt-alloyed HSS to the workpiece, then compare diameter, point, length and shank for the hole and drill.
DeWalt tabless packs add thermal headroom for saws and blowers, but drills rarely use it. Compare the DCB2105, DCB6112, and standard packs.
Screen a Kobalt 24V drill battery by model, USB-C port, capacity and sales window, then follow Greenworks’ free replacement process.
A $199 drill kit faces about $25 from 12.5% pass-through. Compare seasonal discounts and calculate whether buying now or waiting costs less.
See what triggers, gearboxes, and clutches change, how to set drilling speed, and why motor type and manufacturer approval determine controller fit.
There is no single best wood drill bit for every job. A bit that makes a fast service hole through a stud may be a poor choice for a visible dowel joint, while…
An impact driver is primarily a compact tool for driving screws and smaller fasteners. An impact wrench is primarily a higher-torque socket tool for nuts,…
Canada’s list includes HS 8467 motorized hand tools and HS 8207 drilling tools, but the added duty applies only to qualifying U.S.-origin goods.
Model numbers settle Milwaukee’s XC5 naming confusion. Compare the new 5Ah pack with the old XC5.0, XC6.0 High Output, and Forge XC6.0.
Tungsten shortages have pushed carbide costs higher. Compare carbide, cobalt and HSS by material, breakage risk, expected life and cost per hole.
Porcelain is dense, abrasive, and brittle. A bit advertised for “tile” may still be wrong for porcelain, the required hole diameter, the cooling method, the…
Those are not equivalent setups.
Editorial method: This guide compares published tooling charts, commercial tap-and-drill sets, and clearly identified user reports. Q and R were not…
Start with Q at 0.332 inch for a general chart lookup. Some matched kits specify R at 0.3390 inch, so check the exact tap instructions before drilling.
It may be more appropriate for a difficult glaze, a product-rated range of harder tile materials, or a large opening requiring a core-bit format.
37/64 in is commonly listed, while Allied Machine lists 9/16 in for NPT/NPTF without a taper reamer. Exact tap data or the approved process controls the choice.
That number can be a nominal rating in one battery family and a full-charge limit in another. Choose by chemistry, part number, terminals and approved charger.
Use a 5/16-inch bit for a conventional 3/8-16 cutting tap. For a forming tap, check the manufacturer's drill-size data.
Reduce pressure near breakthrough, stop after penetrating the tile, then treat the substrate and anchor as a separate stage rather than drilling straight on.
Larger openings favor core hole saws; smaller holes may suit a solid option explicitly rated for granite. Verify workable depth, connection and wet/dry rating.
It works best when the material is relatively thin, the target diameter is within the bit's marked range and a shallow through-hole is acceptable.
Use a 7/16-inch drill for the tapered 1/4-18 NPT thread. The straight 1/4-18 NPS form instead takes a 29/64-inch drill.
A clean entrance does not promise a clean back face. You'll know when its geometry helps and when backing, feed control or a different bit matters.
Rigid production may justify solid carbide, while handheld metal repair may favor cobalt HSS. Masonry needs a purpose-built carbide-tipped bit.
A specialized carbide-tipped die drill may suit precision hardened-steel work, while a locksmith or broken-fastener drill may be better for rough access.
A sharp HSS bit can drill common annealed stainless. Chips from both flutes suggest it is cutting; a bright, polished dimple means stop and reassess.
Choosing a sound match requires four checks: alloy or credible hardness, hole requirements, the drill's stated application and the available machine.
Hard layers, coarse fragments, groundwater and collapsing walls can make practical depth much less than the tool's assembled length suggests.
Both sizes are documented: 23/32 in. appears in supplier charts, individual tap listings and matched sets. The exact tap's instructions resolve the conflict.
Step bits drill sheet metal in graduated diameters and deburr the hole. Other choices prioritize clean wood holes, deep timber, masonry or large openings.
