9/64 drill bit split point is a Castle woodworking drill bit designed for accurate boring jobs across a range of materials. The split point geometry starts the hole cleanly, which helps the bit stay on line when you are drilling into challenging surfaces. Because this bit is suited to all materials, it carries over from solid stock to sheet goods without a changeover, supporting uninterrupted workflows. The bit is identified as a Castle Castle Machine Replacement Bits Drill Bits 9/64, B01964, tying it directly to Castle woodworking operations that specify this part number. Its role as a replacement bit keeps existing Castle setups boring to the same size, which is important when hole size is tied to downstream fasteners. Being a drill bit within the Bits, Blades and Cutters, Boring and Drilling class, it fits naturally into cabinet, furniture, and general woodworking processes where consistent hole sizing matters.
This 9/64 inch drill bit, split point, is configured so the cutting edges form a self-centering tip, which reduces walk at the start of the hole and supports accurate placement on layout marks. When working in plywood and other composite panels, that split point resists the grain-related deflection that often pushes standard bits off line, giving straighter pilot holes. The slip fit with a No. 7 screw means the drilled hole will let the screw slide without binding, which supports joints where the screw is intended to pull two parts together through an oversized clearance hole. With its 1/4 inch shank, the bit interfaces easily with common drill chucks sized for that diameter, and that simplifies switching this bit in and out during production or installation work.
The Castle Castle Machine Replacement Bits Drill Bits 9/64, B01964, fits into woodworking environments that need repeatable pilot and clearance holes. Its classification under Bits, Blades and Cutters, Boring and Drilling places it squarely in drilling stations, handheld drills, and Castle machinery that reference this size. Because the split point woodworking drill bit works on all materials, it carries from hardwood face frames to plywood cabinet boxes and even into other sheet goods in the same workflow. It is particularly valuable when drilling along an extremely tough grain pattern like plywood, where panel construction and glue lines can deflect ordinary points. In that setting, the split point helps the bit cut into difficult areas instead of skating, so pilots for No. 7 screws stay aligned along rails, stiles, and cabinet sides.
The stated slip fit between the 9/64 inch hole and a No. 7 screw makes this bit suitable wherever that specific screw size is part of the fastening plan. By giving the screw a slip fit for easy screw insertion, the bit supports joints that rely on the screw to clamp parts together rather than thread into the first component. That helps when drawing face frames tight to cabinet boxes or when using clearance holes in one workpiece with threads biting in the mating piece. The 1/4 inch shank design means the bit seats securely in chucks sized for that dimension, which is common in woodworking drills, so changing from drilling into solid stock to boring in plywood can remain efficient. Because it is identified by manufacturer part B01964, repeat orders match the same geometry and sizing, which helps maintain consistent results across replacement cycles.
The split point woodworking drill bit works on all materials, so it can move between different woods and other workpieces while keeping the same hole size in your drilling setup.
The bit is most useful when drilling along an extremely tough grain pattern like plywood, helping it track straight through glue lines and grain changes that challenge standard points.
A No. 7 screw used with this bit will provide a slip fit for easy screw insertion, so the drilled 9/64 inch hole functions as a clearance hole in many woodworking joints.
The 1/4 inch shank means the bit seats in chucks sized for that diameter, matching many woodworking drills and simplifying tool changes during boring operations.
The bit is identified as Castle manufacturer part B01964 and as Castle Castle Machine Replacement Bits Drill Bits 9/64, which links it directly to Castle applications needing this size.
The split point tip starts the hole cleanly and limits walking on the work surface, which helps place pilots accurately on layout marks in woodworking projects.
The 9/64 inch drill bit, split point, is set up so a No. 7 screw used with this bit will provide a slip fit for easy screw insertion, tying the drilling operation to a specific fastener size. Its performance on extremely tough grain patterns like plywood lets one bit handle common cabinet and furniture substrates without changing tools between panels. With a 1/4 inch shank suited to many woodworking drills and the Castle B01964 identification, this split point woodworking drill bit gives a clear path from part number to hole size and screw fit. Select this Castle Castle Machine Replacement Bits Drill Bits 9/64 when that combination matches your drilling and fastening plan.
