7/8" x 6" Spade Bit, 1/4" Straight Shank

7/8 x 6 Spade Bit For Wood Drilling

7/8 x 6 spade bit gives you a 7/8 inch cutting width and a 6 inch bit length, which produces a hole size suited to many woodworking layouts while giving extra reach for drilling through thicker hard or soft wood stock. The Timberline branding ties this spade bit to a defined product line, so repeat orders match existing bits on the job. As a spade bit in the Boring and Drilling class, it removes wood quickly in general purpose drilling of hard and soft woods and wood byproducts, which supports fast through-holes in cabinet parts or structural members. The 7/8 inch dimension sets a predictable clearance for components that pass through the bored hole, which supports consistent layout.

Key Spade Bit Details For Daily Woodwork

• Precision ground steel cutting profile maintains a defined edge on the 7/8 inch tip, which helps the bit track more accurately in hard and soft woods and reduces wandering as the hole starts.
• Hardened steel body resists wear during repeated general purpose drilling of hard and soft woods and wood byproducts, which supports a more consistent hole size across longer production runs.
• 6 inch overall length reaches deeper through workpieces, which allows boring through thicker panels or stacked material while keeping the shank clear for the drill chuck.
• 1/4 inch straight shank fits drills that accept a 1/4 inch round shank, which simplifies switching between bits when moving from smaller to 7/8 inch holes on the same drill.
• General purpose rating for hard and soft woods and wood byproducts makes this single spade bit suitable for a range of shop materials, which streamlines bit selection during layout and assembly.

Spade Bit Shank And Cutting Geometry In Use

The 1/4 inch straight shank on this spade bit provides a uniform round interface to the drill chuck, which helps grip securely while transmitting torque to the 7/8 inch cutting end. With a 6 inch overall length, the bit extends farther from the chuck, which provides reach for drilling through thicker boards or components in one pass. As a spade bit designed for general purpose drilling of hard and soft woods and wood byproducts, it removes material quickly, which supports faster production drilling in common shop materials. The combination of straight shank and spade geometry concentrates power at the cutting face, which helps maintain hole progress even in denser woods.

Where This Timberline Spade Bit Delivers Value

Using The 7/8 Inch Bit In Wood Projects

This Timberline 7/8 inch x 6 inch spade bit is part of the Bits, Blades and Cutters category under Boring and Drilling, which positions it for drilling tasks in woodworking rather than metal or masonry work. Its general purpose design for hard and soft woods and wood byproducts means the same bit can be applied to solid lumber, plywood, or other wood-based sheet goods, which supports consistent workflow when moving between materials in the same project. The 7/8 inch cutting size sets a fixed diameter that repeats from hole to hole, which matters when routing wiring, placing tubing, or creating clearance holes where uniform sizing keeps assemblies aligned. Because the bit length is 6 inches, it can pass through thicker material sections in a single drilling operation, which reduces the need to drill from both sides to meet a center point.

Details That Support Repeatable Hole Quality

The precision ground construction of this spade bit shapes the cutting edges accurately, which helps the bit engage the work cleanly and track straight as drilling progresses in hard and soft woods. Hardened steel further stabilizes those cutting edges under load, which supports maintaining the 7/8 inch hole dimension across many cycles rather than widening unpredictably. The 1/4 inch straight shank offers a consistent round surface for the drill chuck jaws, which promotes stable rotation and reduces slippage that could mark the work surface. As a spade bit dedicated to general purpose drilling of hard and soft woods and wood byproducts, it is tuned to remove chips efficiently in these materials, which helps clear the hole and keeps the cutting end working instead of binding. Together, these details support repeatable hole quality that aligns with layout marks and assembly requirements across production or installation work.
