    1" x 6" Spade Bit, 1/4" Straight Shank

    Description

    1 Inch x 6 Inch Spade Bit For Wood Drilling

    1 inch x 6 inch spade bit gives a 1 inch diameter bore over a 6 inch length, so installers can open up clearance holes or runlines through typical framing or cabinet stock in a single pass. Timberline branding identifies a dedicated woodworking bit, aligning with the needs of cabinet, furniture, and millwork shops that drill wood daily. As a spade bit in the boring and drilling class, it cuts flat-bottom style holes that suit routing wires, plumbing penetrations, or hardware clearances where clean lateral space matters. The 604-600 manufacturer part number ties the bit to its specific size and geometry, which supports repeat ordering when a crew standardizes on this cut. Wurth Baer Supply positions this bit in its professional drilling range, connecting it to workflows that expect consistent hole sizing across many panels or studs.

    Spade Bit Details That Support Woodworking Jobs

    • Precision ground construction keeps the cutting edges true, which helps the bit track straight through wood panels or studs for more accurate hole placement and less wandering.
    • Hardened steel body resists wear at the cutting tips, supporting longer service life when drilling repeated holes in jobsite or shop wood conditions.
    • General purpose design for hard and soft woods gives one bit that handles framing lumber, hardwood components, and softer sheet goods without swapping tools mid-task.
    • Suitability for wood byproducts means it can drill into materials like composite or engineered wood, simplifying boring operations across mixed cabinet or casework projects.
    • Timberline brand alignment with woodworking focuses the bit on wood applications, helping crews match their boring tools to cabinet, furniture, or fixture installation work.

    Shank And Length Setup For Drilling Workflow

    The 6 inch length provides reach through thicker stock or stacked components, allowing installers to drill across cabinet sides, rails, or wall assemblies from one side. A 1/4 inch straight shank interfaces with drivers and drills sized for that shank, so crews can use common 1/4 inch chucks or bit-holding systems already in their kits. Being in the boring and drilling category highlights its primary role in hole creation, which simplifies tool selection when technicians move from pilot bits to larger clearances on the same job. The 1 inch cutting width gives predictable clearance for lines or fasteners that fit comfortably within that diameter, supporting planning for grommets, pass-throughs, or service penetrations.

    Using This Timberline Spade Bit In Daily Work

    Where This 1 Inch Spade Bit Performs Best

    The 1 inch x 6 inch spade bit fits tasks that call for a 1 inch opening in wood, such as creating pass-throughs in cabinet backs, drilling through studs, or cutting clearance in wood platforms. Its general purpose rating for hard and soft woods means the same bit can move from hardwood face frames to softwood blocking without changing tooling between operations, which helps keep production lines or jobsite workflows moving. Suitability for wood byproducts extends that coverage to engineered wood components frequently found in cabinets and fixtures, reducing the need to separate tooling by panel core. Within Wurth Baer Supply's woodworking-focused inventory, this Timberline spade bit aligns with trade users who routinely bore holes in mixed wood materials.

    Details That Support Repeatable Hole Quality

    Precision ground cutting edges help maintain the 1 inch diameter consistently from hole to hole, which matters when fittings, grommets, or lines must pass through without binding. Hardened steel resists deformation at the cutting lips, so the bit maintains its geometry longer under repeated drilling, supporting consistent entry and exit quality in wood parts. The 6 inch length gives the operator room to clear chips along the flutes while still reaching through typical cabinet or wall sections, which helps manage heat and cutting efficiency. The 1/4 inch straight shank provides a stable grip in matching chucks, reducing slippage that could affect hole location or diameter during production work. Together, these details support crews that depend on predictable bores to assemble cabinetry, fixtures, or wood structures without constant bit changes.

    Key Questions About This Timberline Spade Bit

    What materials is this Timberline spade bit designed to drill?

    The Timberline 1 inch x 6 inch spade bit is designed for general purpose drilling of hard woods, soft woods, and wood byproducts, so it covers common cabinet, furniture, and construction lumber materials.

    How does the 1 inch x 6 inch size affect typical drilling tasks?

    The 1 inch cutting size produces a 1 inch bore, while the 6 inch length allows drilling through thicker wood sections or assemblies from one side, which supports pass-through and clearance hole work.

    What is the role of the 1/4 inch straight shank on this bit?

    The 1/4 inch straight shank fits tools sized for a 1/4 inch shank, giving a consistent interface with compatible drills and drivers for stable driving and accurate hole placement.

    Why does precision ground construction matter for this spade bit?

    The precision ground cutting edges help the bit stay true to its 1 inch diameter and track straighter through wood, which supports clean, repeatable holes during production or installation.

    How does hardened steel affect performance in wood drilling?

    The hardened steel body improves wear resistance at the cutting edges, so the bit can maintain its cutting shape over more holes in hard woods, soft woods, and wood byproducts.

    What does Timberline part number 604-600 indicate?

    Timberline part number 604-600 identifies this specific 1 inch x 6 inch spade bit, which supports consistent reordering when crews standardize on this size for wood drilling tasks.

    Selecting This Spade Bit For Wood Drilling Work

    The 1 inch x 6 inch spade bit from Timberline combines a 1 inch cutting diameter, 6 inch length, and 1/4 inch straight shank with precision ground, hardened steel construction for general purpose drilling in hard woods, soft woods, and wood byproducts. That set of characteristics suits cabinet shops, installers, and carpenters who require a predictable 1 inch bore across varied wood-based materials. For teams sourcing through Wurth Baer Supply, this spade bit aligns with woodworking-focused inventories, making it a direct option when specifying boring tools for upcoming wood or wood byproduct drilling work.
