What’s the difference between a chucking reamer and a construction reamer?
Chucking reamers are precision tools used in machine setups for fine hole finishing; construction reamers are heavier-duty and used in fabrication environments for enlarging and aligning holes.
What’s the difference between a spade bit and an auger bit?
Spade bits are faster but rougher. Auger bits are slower but cleaner and better for deep or repeated stud drilling.
What’s the difference between HSS and cobalt reduced shank drill bits?
HSS bits are made from high-speed steel for general-purpose drilling in softer metals, wood, and plastics. Cobalt bits contain 5–8% cobalt for added hardness and heat resistance, making them better for stainless steel and other hard alloys.
What’s the difference between HSS and cobalt Silver & Deming bits?
HSS is economical and suitable for softer materials; cobalt adds hardness and heat resistance for tough metals.
What’s the lifespan difference between HSS and cobalt reduced shank bits?
Cobalt bits can last 2–4 times longer in hard metals compared to HSS, assuming proper use and cooling.
What’s the maximum hole size I can drill with a reduced shank bit?
It depends on the bit — reduced shank designs can go up to 1-1/2" cutting diameter for a 1/2" shank.
What’s the typical size range for Silver & Deming bits?
They usually start at 9/16" diameter and go up to 1-1/2" diameter, all with a 1/2" shank.
When should I use a bridge reamer instead of a construction reamer?
Bridge reamers are best when hole misalignment is common — their long taper helps guide and center the reamer quickly. Construction reamers excel at enlarging holes to exact diameters.
Where are Stanley HD-45 & Skil 736 masonry drill bits manufactured?
Manufacturing locations vary by supplier and model—check packaging or the manufacturer’s website for specific origin details.
Which drill bits are masonry?
Any bit with a tungsten carbide tip designed for drilling concrete, brick, block, or stone.
