Twelve kits fall into three families: twist drill bits, carbide burrs and oscillating multitool accessories. Drill sets run from 13 to 115 pieces, and burr sets hold between 8 and 20. Start with the tool already in your hands, whether that is a drill or driver, a rotary tool or die grinder, or an oscillating multitool, and the family picks itself.

What sets CaRoller tools apart

Cobalt alloyed into the steel
Four of the drill sets are M35 high speed steel with 5% cobalt in the alloy itself. Those four are the ones matched to stainless steel, cast iron and titanium alloy, and the 115-piece box adds hardened steel to that list. On the 29-piece cobalt set an amber coating sits over the cobalt steel.

A 135-degree split point on every twist bit
Cobalt or titanium-coated, every drill bit in the range is ground to a 135-degree split tip. That intelligent self-centering shape prevents walking when the bit first meets smooth metal. Behind the tip, a fully ground twist design ensuring cooler drilling performance by decreasing friction.

Burrs on two shank diameters
Each tungsten carbide burr is double cut, with two cutting edges, and sits on either a 3mm (1/8 inch) or a 6mm (1/4 inch) shank. Thin shanks belong to detail carving and engraving on a rotary tool. Heavy material removal calls for the thicker shank and a die grinder to drive it.

Cases that keep sizes in order
The 13, 21 and 115-piece cobalt sets and the black and gold set ship in indexed metal boxes, so each diameter returns to its own slot. The larger cobalt boxes add a built-in clip. Both multitool kits travel in a moisture-proof, dust-proof plastic box instead.
Steels, coatings and how to look after them
Three drill steels appear across the range. M35 cobalt, with 5% cobalt, goes into the 13, 21, 29 and 115-piece cobalt sets. The black and gold set is high speed steel with an amber coating over a black oxide finish, while the hex shank set is high speed steel with a titanium coating. On the 29-piece cobalt set, the amber coating adds wear resistance and ensures long-lasting use on hard plastics, cast iron and steel.
Burrs are tungsten carbide throughout. Both 1/4 inch shank sets work metal, wood, plastic, stainless steel and marble, and the 1/8 inch sets handle lighter carving and engraving on the same materials a rotary tool can reach.
Care starts with matching steel to the job. The black and gold bits drill aluminum, copper and low alloy steel but are not meant for hardened or stainless steel, so save the cobalt bits for those. In plastic, keep the black and gold bits below 500 RPM. Returning each bit to its slot after use stops sizes from mixing, and the sealed plastic boxes keep multitool blades dry and free of dust between jobs.

A shop working from letter and wire sizes
Drawings that call out letter or numbered gauges leave a fractional-only set short. The 115-piece box holds 29 fractional bits, 26 letter sizes from A to Z and 60 wire sizes numbered 1 through 60, so a small machine or fabrication shop can keep one metal drill index on the bench rather than three.

Handymen carrying a quick-change driver
Construction workers and handymen who already drive screws with a quick-change driver can drill without swapping to a chucked drill. The 13-piece titanium set has 1/4 inch hex shanks, sizes up to 1/4 inch and a round carrying case with a belt clip, which suits occasional house projects and hobby drilling.

Hobby carving with a rotary tool
Hobbyists engraving or carving small detail work fit the ten-piece 1/8 inch carbide burr set. Its clear case lets you see every shape before opening the lid. Once a project moves to heavy stock removal, the 1/4 inch shank sets take over.

Remodeling drywall and plasterboard
Remodelers who cut openings in drywall and then smooth the edges need blades and sandpaper together. One kit pairs 11 different oscillating blades with 2 pads and 60 sandpapers for cutting, grinding, polishing and shoveling work on drywall, plasterboard, wood and plastic.
About the CaRoller range
The collection covers three kinds of shop work: drilling with twist bits, shaping and engraving with carbide burrs, and cutting or sanding with oscillating multitool accessories. Drilling takes the largest share, six sets that differ mainly in steel, bit count and shank.
It suits handymen, woodworkers, hobby builders and metalworkers who put holes in steel and sheet metal regularly. Anyone after a bit set for metal should look at the cobalt sets first. Titanium and black and gold bits lean toward wood, plastic, aluminum and lighter household drilling.
Limits are easy to spot. No fractional bit in the collection goes past 1/2 inch, the 21-piece set stops at 3/8 inch, and both compact 13-piece sets end at 1/4 inch. If your work needs larger holes than those, plan around that ceiling before you order.
