Slim’s inventory includes high-speed steel bits, wood-boring bits, SDS-Plus and SDS-Max bits, multi-material bits, tile and glass bits, countersinks, step bits, hole saws, arbors, pilot bits, and related accessories. Brands, dimensions, specifications, and quantities may vary by store.
Find high-speed steel drill bits for approved metalworking, fabrication, installation, maintenance, and general drilling applications.
Slim’s inventory includes standard, aircraft-length, extended-length, and double-ended bits from manufacturers such as Alfa Tools and Galaxy Drill Bits. Available listings cover individual fractional sizes, larger diameters, and long-reach configurations.
The inventory also includes select cobalt, impact-ready, step-drill, tap-and-drill, and countersink products from DEWALT, Milwaukee, Fuller, and other manufacturers.
Before selecting a metal-drilling bit, confirm the type and thickness of metal, required hole diameter, drilling depth, chuck size, tool speed, and whether cutting fluid is recommended.
Shop wood-boring bits for framing, rough carpentry, electrical installation, plumbing, remodeling, cabinetry, and general woodworking.
Slim’s inventory includes:
DEWALT carries a broad selection of spade, auger, and self-feed bits in the inventory. Bosch Daredevil and Diablo wood-boring products are also represented.
Choose the bit according to the wood type, required diameter and depth, tool torque, shank design, and desired finish.
Find rotary-hammer bits for drilling into approved concrete, block, brick, stone, and masonry.
Slim’s inventory includes extensive SDS-Plus and SDS-Max selections from Bosch, Diablo, DEWALT, Milwaukee, Relton, and Galaxy Drill Bits. Products represented include two-cutter and four-cutter bits, extended-length bits, core bits, dust-extraction bits, and specialty rebar-cutting products.
SDS-Plus and SDS-Max are different attachment systems and are not interchangeable.
Before purchasing, confirm:
Slim’s inventory includes SDS-Max core bits and related pilot components for creating larger openings in approved concrete and masonry materials.
Available listings from Bosch and Diablo include core-bit bodies, pilot bits, adapters, rings, pins, and other system components.
Specialized inventory also includes rebar-cutting bits and long-reach masonry products. These products should be used only with compatible equipment and according to the tool and bit manufacturers’ instructions.
Core drilling and concrete drilling may require dust extraction, water delivery, respiratory protection, and other jobsite controls.
Multi-material bits are designed for approved drilling across more than one material category.
Slim’s inventory includes multi-material products and sets from Diablo, Milwaukee, and DEWALT. Depending on the individual bit, approved materials may include combinations of wood, metal, plastic, block, brick, tile, or masonry.
“Multi-material” does not mean that a bit is suitable for every surface. Review the manufacturer’s approved material list, tool requirements, and operating instructions before use.
Find specialized bits for approved tile and glass drilling applications.
The inventory includes individual tile and glass bits and multi-piece sets from Bosch and Milwaukee, along with additional specialty products from Diablo and DEWALT.
Before drilling, confirm the exact material, thickness, bit diameter, cooling requirements, tool speed, and whether hammer action must be disabled.
Tile and glass can crack or chip when drilled with the wrong bit, pressure, speed, or technique.
Step bits can create or enlarge holes in approved sheet materials, while countersinks can prepare recesses for screw heads or support other fastening applications.
Slim’s inventory includes step-drill products from Milwaukee and DEWALT, along with tapered drill bits and countersinks from Fuller.
Select the product according to:
Slim’s carries hole saws for construction, electrical, plumbing, mechanical, woodworking, metalworking, tile, and installation work.
The inventory includes an extensive Lenox hole-saw selection, including:
Slim’s inventory includes impact-ready and hex-shank drill bits designed for use with approved impact drivers and drills.
Products represented include DEWALT impact-ready drill bits and sets and Milwaukee Shockwave drill-bit products.
Do not assume that every drill bit, extension, or accessory is impact-rated. Check the manufacturer’s rating and confirm the shank, chuck, speed, and application requirements.

| Anchors and concrete fasteners | The exact bit diameter and depth required by the fastener manufacturer |
| What to Confirm | Why It Matters |
| Tool type and model | Determines the required chuck, shank and operating system |
| Attachment system | Standard chuck, hex shank, SDS-Plus and SDS-Max are not interchangeable |
| Bit diameter | Controls the finished-hole size and fastener compatibility |
| Working and overall length | Determines drilling depth and available reach |
| Material | Affects bit construction, cutting geometry and operating requirements |
| Application | Pilot hole, through-hole, anchor hole, countersink, enlargement or core drilling |
| Tool speed and mode | Some bits require specific speeds or prohibit hammer action |
| Cooling or lubrication | Certain metals, tile and specialty materials may require approved cooling |
| Fastener requirements | Anchor and fastener instructions determine the required hole dimensions |
| Quantity and workload | Repeated drilling may require a different product than occasional use |
Do not choose a bit based only on its diameter or appearance. Bits that look similar may be designed for different tools, materials, speeds, and applications.
Bring the tool model number, current bit, product packaging, fastener instructions, or a clear photo when you need help checking compatibility.
When drilling for an anchor or concrete fastener, the required bit diameter and hole depth should follow the fastener manufacturer’s installation instructions.
Confirm the base material, anchor type, fixture thickness, embedment, minimum hole depth, edge distance, spacing, hole-cleaning procedure, and installation tool before drilling.
Do not substitute a different drill-bit size unless the anchor or fastener manufacturer specifically allows it.

Tell our team what you are drilling, the required hole size and depth, and the tool you plan to use. That information can help narrow the available options quickly.
Inspect the bit, tool, workpiece, and work area before drilling.
Do not use a bit that is bent, cracked, chipped, excessively worn, loose in the chuck, incorrectly sized, or not approved for the tool or material.
Follow the tool and bit manufacturers’ instructions for installation, speed, drilling pressure, hammer mode, cooling, lubrication, dust control, personal protective equipment, workpiece support, and safe operation.
Disconnect the drill from its power source or remove the battery before installing, removing, or inspecting a bit.
Inspect the drilling area for concealed wiring, plumbing, fasteners, reinforcement, and other hazards before beginning work.
