Sanding Discs & Abrasives

Random Orbital Sander - Grit Progression

60-80 grit: Heavy stock removal, shaping
100-120 grit: General purpose, prep for finishing
150-180 grit: Final sanding before stain/paint
220 grit: Between finish coats, ultra-smooth

Belt Sander - Heavy Removal

40-60 grit: Aggressive stock removal, floor refinishing
80-100 grit: Smoothing after rough sanding
120+ grit: Final passes (follow with orbital for best finish)

Detail Sander (Mouse/Delta)

Same grit progression as orbital
Best for corners, edges, tight spaces
Less aggressive than larger sanders

Blade/Bit Selection Tips

More teeth = smoother cut: But slower and generates more heat
Fewer teeth = faster cut: But rougher finish
Blade diameter matters: Larger blades cut deeper but require more power
Carbide-tipped lasts longer: 10-50x longer than HSS, worth the cost for frequent use
Match shank size: 1/4" and 1/2" router bits aren't interchangeable without adapter
Don't exceed max RPM: Check blade/bit rating vs. tool speed
Replace dull blades promptly: Dull blades burn wood, require excessive force, dangerous
Clean pitch buildup: Resin/pitch reduces blade efficiency - clean with blade cleaner

Safety & Maintenance

Safety:

Always unplug tool before changing blades/bits
Wear safety glasses and hearing protection
Secure workpiece before cutting
Let blade/bit come to full stop before setting down tool
Never remove blade guard (circular saws)

Maintenance:

Store blades flat or hanging to prevent warping
Clean resin buildup regularly with blade cleaner
Sharpen or replace when cutting quality degrades
Check for cracks, missing teeth, or damage before use
Label blades/bits by material for quick selection

Frequently Asked Questions

How many teeth should my circular saw blade have?

Tooth count depends on the material and cut quality needed. For framing lumber where speed matters more than finish, use 24-tooth blades. For general-purpose cutting of hardwood and plywood, 40-60 teeth provides a good balance of speed and finish quality. For fine finish cuts on plywood, melamine, or veneer, use 60-80 teeth for minimal tearout. More teeth = smoother cut but slower feed rate and more heat buildup. Match the blade diameter to your saw (typically 7-1/4" for standard circular saws).

What drill bit should I use for metal?

For mild steel, use HSS (high-speed steel) twist drill bits at low-medium speed (500-1000 RPM) with cutting oil. For stainless steel, use cobalt or carbide bits at very low speed (200-500 RPM) with constant pressure - stainless work-hardens if you back off. For aluminum, regular HSS bits work well at high speed (2000+ RPM). Always start with a center punch to prevent walking, use cutting fluid for steel, and clear chips frequently. For thin sheet metal, use unibit (step drill) to prevent grabbing.

Why does my saw blade burn the wood?

Wood burning usually indicates a dull blade, wrong blade for the material, feeding too slowly, or misaligned fence/blade. Dull blades generate friction heat instead of cutting cleanly - replace or sharpen if teeth are worn. High-tooth-count blades (80+) generate more heat than necessary for rough work. Feeding too slowly keeps the wood in contact with the blade too long - maintain steady, moderate feed pressure. Also check that your blade is parallel to the fence; misalignment causes the back of the blade to rub and burn the cut edge.

What's the difference between upcut and downcut router bits?

Spiral upcut bits pull chips up and out of the cut, leaving a clean bottom but potentially causing tearout on the top surface - best for deep mortises and through cuts where you can sacrifice the top. Downcut bits push chips down, leaving a clean top edge with no tearout - ideal for plywood, veneer, and visible surfaces, but chips can pack in deep cuts causing heat and burning. Compression bits have both upcut and downcut flutes and are the best choice for cutting sheet goods when both faces will be visible.

How do I prevent plywood from splintering when cutting?

Use a high-tooth-count blade (60-80 teeth) with ATB or Hi-ATB grind - more teeth with alternating bevels slice veneer cleanly. For circular saws, cut with the good face down since teeth exit through the top. For table saws, good face up. Apply masking tape along the cut line to support the veneer fibers, or score the cut line with a utility knife first. For jigsaws, use a reverse-tooth blade or cut with the good face down. Feed at a steady, moderate pace - too fast causes tearout, too slow causes burning.

When should I replace my saw blade?

Replace or sharpen your blade when: cuts require more feed pressure than usual, you see burn marks on the wood, the blade produces excessive sawdust instead of chips, cut edges feel rougher than they should, or you notice the blade is making more noise. Inspect blades for missing or chipped carbide teeth, cracks in the blade body, or excessive pitch buildup. Quality carbide blades can be professionally sharpened 3-5 times before replacement. Clean pitch buildup regularly with blade cleaner to extend blade life.
